[Season 1 !Season 2 !Season 3 !Season 4 ]
A hundred years in the future, and Earth has been rendered uninhabitable by radiation. The human race survives aboard a space station named the Ark, where draconian laws are in place. All criminals aged over 18 are executed, so when the rulers decide to lower the population and explore Earth the only convict labour they can exploit is the under-18s. It does not hurt that the teenagers are all incredibly photogenic.
The protagonist is Princess Clarke, daughter of the ruling elite who has been jailed for political reasons. The others are a mix of archetypes, with a few interesting characters thrown in. The ruler’s son has got himself arrested because he is the Princess’s best friend, or at least he was until his dad executed her dad.
The drop-pod goes slightly off-course, because the tech has not been used in a hundred years. The teenagers split into two groups. The heroine and a handful of archetypes (rebellious love interest, brunette love rival, comic relief stoners) go looking for food. The rest of them turn into a Lord of the Flies gang.
Back on the Ark, the Ruler (Isaiah Washington – ) has been incapacitated. The Princess’s mother ( Paige Turco ) tries to save his life. Councillor Kane (Henry Ian Cusick - Lost ) is next in line of succession, and he enforces the law blindly. His wife ( Kelly Hu ) is Turco’s best friend, but he will not let that stop him. Turco is keen to present him as a villain, but the Ark’s resources will run out in four months time so he really has limited choices.
The survivors get back to camp, and send out a rescue mission. Princess Clarke and Finn the cool guy are going back to save their friend. They bring along the Ruler's son, plus Bellamy the Assassin (Bob Morley - Road Train AKA Road Kill ) and his sidekick Murphy (the stepbrother from Continuum ). Unfortunately, the locals have strung their victim up as live bait. But who or what are they trying to lure out?
Octavia the brunette love rival ( Marie Avgeropoulos ) is left at the camp. One of Bellamy's goons is assigned to keep the boys away from her. Unfortunately she is a flirty little nympho, so putting her with dozens of immature criminal delinquents is a recipe for disaster. But at least she tries to help Jasper the nerd (Devon Bostick - Being Erica ) reverse-engineer the transmitter cuffs so they can try to signal the Ark for help.
Back on the Ark space-station, a girl space-engineer named Raven ( Lindsey Morgan ) gets suspicious. The drop-pod is missing, and the prison is on lockdown. The Princess’s mother ( Paige Turco ) must prove that Earth is surviveable, to stop Councillor Kane (Henry Ian Cusick - Lost ) from culling two hundred citizens.
Bellamy the assassin (Bob Morley - Road Train AKA Road Kill ) and his team go hunting for food. The local animals are mutated, and their meat is probably tainted with radioactivity, but it is a choice between taking a risk or starving to death. A pre-teen girl tags along, and the boss takes her under his wing.
They discover that the weather patterns have changed. Occasionally the area is prone to huge green clouds of mustard gas that cause severe chemical burns to any exposed skin they touch.
Jasper the nerd (Devon Bostick - Being Erica ) and Octavia the hot chick ( Marie Avgeropoulos ) stay at base-camp, where they try to heal the gut-stabbed guy. He is in a lot of pain, but nobody gives him a belt to bite down on. His screams do not help camp morale.
This is only the third episode in, but recurring characters start to die. Yes, this show is actively working to create a genuine sense of jeopardy for the characters.
With one of the survivors murdered at the end of the previous episode, everyone thinks the Grounders are responsible. Then the murder weapon gets discovered – it is a knife that Murphy (Richard Harmon - Continuum ) claims he lost. Bellamy the Assassin (Bob Morley - Road Train AKA Road Kill ) wants to maintain the status quo, but the Princess decides to tell the whole camp. Then she acts SURPRISED when the camp full of teenage degenerates forms a lynch mob!
Nobody except the Princess cares about the victim, and she only cares because she feels guilty about being mean to him. Everyone else had as much motive to kill the guy as the actual murderer. And poor old Murphy is an easy scapegoat because he has been a complete git to everyone. Of course, he only did this to enforce Bellamy’s rule – but even Bellamy is willing to go along with the mob in order to maintain his own position!
The real murderer is revealed, and pretty much gets away with everything. Murphy is aggrieved at being the victim of mob justice, and believes that the killer should be punished in the same way.
The drop-pod lands, and Bellamy the Assassin (Bob Morley - Road Train AKA Road Kill ) decides once again to put his own welfare ahead of the rest of the group. He has already inspired the teenage degenerates to embrace a philosophy of Whatever the hell we want. As well as sacrificing them by denying them all support from the Ark, he will also allow the Ark to sacrifice
Paige Turco has failed in her attempts to contact the kids. The deadline has passed, so now 300 persons must be sacrificed so there is enough oxygen for everyone else. The Chancellor is unhappy about this state of affairs, and even Councillor Kane (Henry Ian Cusick - Lost ) is reluctant to go through with it. But the Princess’s mother does just what her daughter did last episode – she leaks the info to the general public, potentially causing civil war. Like mother, like daughter!
Felix Gaeta ( BSG 2003 ) is lurking in the background as one of the Chancellor’s minions, His hair is greyed-up, but it is still him. Will he play a major part in developments, as he did on the Galactica?
Also, nobody notices that Bellamy’s sister Octavia ( Marie Avgeropoulos ) gets lost in the woods ... where the Grounders are known to hang out!
Bellamy (Bob Morley - Road Train AKA Road Kill ) finally realises that Octavia ( Marie Avgeropoulos ) is still missing. He leads a small team to track her, and they follow her into Grounder territory. Unfortunately the Grounders start to pick them off, one at a time.
Bellamy has flashbacks to his upbringing with his sister, hiding her under the floor every time friendly guard Fulvio Cerce tipped them the wink. The old guy even got Bellamy a job as a trainee guard. However, the one time Bellamy indulged his sister's curiousity about the rest of the Ark, it ended predictably badly.
Raven and the Princess are left together back at the camp. How long will it take for Raven to work out what happened between her BF and the Princess?
Finn has been stabbed, so the Princess tries to patch him up. Unfortunately the knife was poisoned. The Grounder is a prisoner now, but he refuses to speak or acknowledge any words in English. Bellamy (Bob Morley - Road Train AKA Road Kill ) tortures him anyway, with the Princess's backing. Octavia ( Marie Avgeropoulos ) is the only person to object.
Luckily, the Princess can now ask her mother ( Paige Turco ) for advice because the radio link is fixed. With Mom kicked off the governing Council, Kate Vernon is eager to get the vacant seat. Yes, there is a hitherto-unmentioned political faction aboard the Ark. And with Councillor Kane (Henry Ian Cusick - Lost ) visibly sickened by the 300 deaths he had to order, it now puts Ms Vernon as the main suspect behind the assassination attempt.
As grim as this show is, the bodycount could actually get much higher. Only a third of the Ark's population are going to survive the re-entry as they try to land on Earth!
The Ark gets word to the 100 about a supply depot nearby. The Princess and the assassin go looking for it.
The Conspiracy aboard the Ark get word to one of Bellamy's sidekicks. This is the problem with sending a gang of teenage reprobates - the bad guys can easily get leverage on one of them. And Bellamy (Bob Morley - Road Train AKA Road Kill ) knows about the Conspiracy, so he is an obvious target for house-cleaning.
The Grounder is still being held captive in the camp. Octavia ( Marie Avgeropoulos ) tries to help him.
The Ark is preparing to send a military force down to wipe out Grounder resistance. Octavia ( Marie Avgeropoulos ) wants to make a peace treaty, so she arranges a meeting for Princess Clarke with the Grounders’ Princess, Anya ( Dichen Lachman ). However, she is nervous and secretly arranges for Bellamy (Bob Morley - Road Train AKA Road Kill ) and some others to follow. But with Bellamy’s track record, can he be trusted not to mess it up?
On the Ark, the people celebrate Unity Day. The space stations all joined together for mutual benefit. But the Conspiracy use this as their opportunity to target the Chancellor for assassination. This leads to a climactic confrontation over the station’s drop-pod. As the villains rightly point out, two thirds of the population will have to be abandoned to the Ark so that the Elite can return to Earth!
Raven the girl mechanic has been hand-loading bullets using gunpowder. Strange she does not have a modern smokeless propellant like cordite.
The teenagers investigate the landing-pod’s arrival site. There is no sign of the Princess’s mother ( Paige Turco ), and there is no further contact with the Ark. Almost as if contact was cut at the station’s end.
Murphy (Richard Harmon - Continuum ), last seen being exiled by Bellamy (Bob Morley - Road Train AKA Road Kill ), returns to camp. He claims he was tortured by the Grounders, and his wounds support his claims. Unfortunately people start bleeding from their eyeballs. It appears the Grounders infected him with weaponised Ebola, to soften up the survivors before the big attack at dawn.
Raven the girl mechanic has gunpowder, and rocket fuel from the landing pod. She can make a bomb and blow up the bridge. Finn, her boyfriend, volunteers to deliver the bomb. Jasper the nerd (Devon Bostick - Being Erica ) is playing up his hero act from last week, and thinks he is a good enough shot to detonate the bomb.
We finally discover what happened aboard the Ark. Councillor Kane (Henry Ian Cusick - Lost ) teams up with a typically insubordinate young tech. The good news is, they do not have to decide which section of the population to sacrifice. Can he find the Prez (Isaiah Washington - ) and Felix Gaeta ( BSG 2003 )? Not to mention the Princess’s mother ( Paige Turco ). It is nice to see character development for a character portrayed in the pilot episode as being a kill-happy fascist. A pity that nobody ever mentions his wife ( Kelly Hu ).
The kids decide to store all their meat in a smoke-hut. Unfortunately it all goes up in flames, but nobody suspects Murphy (Richard Harmon - Continuum ) of sabotage. The Hundred must send out hunting parties to get more meat.
The Grounders’ Princess, Anya ( Dichen Lachman ) kidnaps her counterpart. Somehow she knew that the blonde is the Hundred's medic. She wants the kids to heal her second in command, a teenage girl who was caught in the explosion last week. Either the kids heal the girl, or the Grounders will kill Finn.
The Grounders are a barbaric culture. They record their kills as scars on their shoulder - even the young girl has five of them. Leaving alone the issue of Child Soldiers (after all, the Hundred are under eighteen) there is the evidently massive mortality rate. And they expect the Princess to help them under duress, even though they will probably kill Finn (and the others) anyway.
Raven, the other typically insubordinate young tech, rigs the Hundred up some walkie-talkies so they can coordinate units. This means dismantling the aparatus they used for talking to the Ark, but they have lost contact with the Ark again anyway. Also, Raven is jealous of Finn and the Princess. She uses Bellamy (Bob Morley - Road Train AKA Road Kill ) to get her own back.
Princess Clarke is still a prisoner of Anya ( Dichen Lachman ). The Grounders will launch an all-out attack within 24 hours, so they have no need for prisoners. But the Princess discovers that there is something worse than Grounders out there - a tribe of cannibals called the Reapers. You know, kind of like the Reavers in Firefly .
Murphy (Richard Harmon - Continuum ) continues his revenge spree on the ringleaders of the lynch mob. Of course, he was bound to get caught sooner or later. His main target is Bellamy (Bob Morley - Road Train AKA Road Kill ), with good reason. But with a Grounder attack imminent, this kind of in-fighting is wasteful and destructive.
On the Ark, the Prez (Isaiah Washington - ) has given up hope. Councillor Kane (Henry Ian Cusick - Lost ) keeps Gaeta testing potential solutions, but the Ark will crash. Nobody mentions that this will, of course, cause an extinction level event. However, the Ark is made of a dozen different space stations and has a supply of rocket fuel aboard, to use on thrusters. Can anyone work out the blindingly obvious?
The kids try to evacuate, but it is too late. The Grounders have them surrounded, so it is a case of fight or die. The teenagers may have M16 rifles, and a magazine of ammo each (500 rounds split between twenty rifles) but they have no idea of basic infantry tactics. The Grounders are smart enough to draw their fire and make them waste their very limited ammo. Luckily, Raven managed to make some grenades and land-mines before she got injured. Princess Clarke tries to help Raven build a new weapon, using the rocket fuel. Finn goes to the friendly grounder to get anti-coagulant for Raven. Will they all get to safety in time?
The kids’ infantry tactics may suck, but their improvised defensive ideas are pretty good. The Reapers and the grounders are bitter enemies, so the fight between the two groups is impressive. And using the rocket fuel as a weapon allows an impressive climax!
The adults aboard the Ark also get a conclusion, of sorts.
A couple of episodes ago, Anya ( Dichen Lachman ) mentioned The Mountain Men. And now we see why the Grounders were so afraid of them. The only question is, since they evidently knew about the 100 all along, why did they not get involved sooner?
Clarke (the Princess) and her friends are in Mount Weather. Yes, like Valhalla Sector in Jeremiah , some members of the military-Industrial complex have survived. Their security is terrible, as one teenage girl can outwit them single-handed, but maybe that is because they are not bad people. After all, most post-apocalyptic shows (especially The Walking Dead ) tend to portray the darker side of the survival instinct.
Here, the bunker people have saved 48 of the 100 kids. The leader tells Clarke that her people are immune to the radiation, while his are not (so they must remain in the bunker). Could there be a link to the bunker peoples’ motivation for saving the kids?
Lincoln the friendly Grounder is taking Bellamy’s sister Octavia ( Marie Avgeropoulos ) to safety. However, her wound is poisoned so he must trade for the antidote. Back at the lander module Raven is bleeding out, as is Murphy (Richard Harmon - Continuum ). They have each other for company, if nothing else.
Bellamy (Bob Morley - Road Train AKA Road Kill ) and a couple of others are hiding out in the woods. A couple of Grounders survived the battle, so there is still danger. Luckily, the survivors from the crashed space station are in the area.
The Prez (Isaiah Washington - ) is trapped on the final orbiting module. He has his son’s picture to keep him company, and the radio transmitter seems to be operational, but his air supply is running out.
Clarke the Princess investigates deeper into the Mount Weather facility. Jasper the nerd (Devon Bostick - Being Erica ) and the others realise that getting three square meals a day is a good thing, But she is naturally paranoid. Especially when a patrol comes in with injured personnel. One has a gunshot wound that the doctor claims was done by an arrow. The other has radiation sickness that looks horrible to start with, but magically heals rapidly. Could their strange dialysis heart-plugs have something to do with it? And why has the Grounder Princess, Anya ( Dichen Lachman ), not been seen among the survivors?
The station crew have decided to stay put. The Grounders are in the woods, crucifying search parties. Bellamy (Bob Morley - Road Train AKA Road Kill ) and the other survivors want to go looking for Princess Clarke. Unfortunately, the boss decides to invoke the Exodus Charter criminal code – where all felonies get the death penalty. This made a certain amount of sense on the space station, where resources were limited, but none at all on the ground.
Back on the space station, the Prez (Isaiah Washington - ) hears a baby crying. Someone has concealed one on the station, and probably forgotten about it. But since oxygen is running out and the Prez is still grieving from the loss of his son, can he trust his own senses? He has a plan to get Earthside again – there is a missile on a distant section of the station. But if he does a Sandra Bullock and crosses from station to station, then rides the missile to Earth (like in Gravity ) ... where will he land? He could end up anywhere in the USA (if he gets the correct continent!), up to three THOUSAND miles from the other survivors.
Princess Clarke teams up with Grounder Princess Anya ( Dichen Lachman ) to escape. However, things are worse than they thought. We discover how the Reapers became so powerful, and where they get their daily supply of human flesh from.
Lincoln the friendly grounder has been captured by Reapers. Bellamy’s sister Octavia ( Marie Avgeropoulos ) tries to team up with Nyko the medicine man (Ty Olssen - Supernatural ) and the Grounders to save him.
Clarke’s mother admits she was the one who helped Bellamy’s crew escape. But the Acting Chancellor has to make an example out of her, or face open rebellion among the survivors. However, he has a captive Grounder and a plan of his own.
Bellamy’s crew discover some Grounders. Murphy (Richard Harmon - Continuum ) gets used as bait. Finn is now a ruthless psycho, obsessed with getting Clarke back.
Bellamy (Bob Morley - Road Train AKA Road Kill ), Finn and Murphy (Richard Harmon - Continuum ) and the redshirts find one of the other crash sites. The sole survivor is in peril. But what will be the cost if they stop to help her? How many of their own people will they lose while trying to save her?
Anya ( Dichen Lachman ) enslaves Princess Clarke, despite their teamwork escaping the Vamps. Anya wants to take Clarke back to her village as a trophy. Clarke has other ideas, and the story so far has toughened the Princess up quite a bit. Unfortunately the bloodsuckers are still after them! Can they escape with their lives? After all, the bad guys already know that Clarke will head to her camp, which is where they found her the first time. This leads to an all-out slug-fest that technically qualifies as a mud-wrestling cat-fight but is nowhere near as glamorous as that suggests. And who will win the bloody and unglamorous catfight?
Back at the camp, the Operations Manager (Gaeta from Battlestar Galactica 2003 ) and the trigger-happy Security sidekick are in charge. The Acting President Councillor Kane (Henry Ian Cusick - Lost ) is off on his peace mission, but there is no sign of Clarke's mother for some reason. Despite being the highest-ranking leader, and the only Doctor in the camp ...
Raven the babelicious mechanic is back on her feet again, assigned to help a friendly engineer to build a beacon. The guy builds her a special brace for her crippled leg, but despite his flirtations Raven is a mean-spirited bitch. This is regardless of the fact that everyone else has lost more than her.
Finn and Murphy (Richard Harmon - Continuum ) find the Grounder village. They cause a distraction by setting the food-storage hut on fire. Since the neighbours feast on human flesh, cutting out the vegetarian option is not a good idea. Ironically, Stargate: Atlantis repeatedly mocked the idea of causing a diversion by blowing something up. The point is that the thing you burn as a diversion should be more valuable than whatever the enemy thinks they are protecting.
Clarke makes it home, as do Bellamy (Bob Morley - Road Train AKA Road Kill ) and his crew. But Clarke’s mother ( Paige Turco ) is in charge now, and she refuses to let them go out again to find their friends. Yes, she is willing to march them into certain death to save her daughter, but once the Princess is safe then the Queen clamps down on dissent.
The kids are out in the woods again, exploring. Clarke and Finn pair off, although she has doubts about his mental state. Bellamy (Bob Morley - Road Train AKA Road Kill ) and Octavia ( Marie Avgeropoulos ) make a good team.
Clarke's mother ( Paige Turco ) trusts Raven again, which is lucky because Raven discovers that Mount Weather is jamming all frequencies. All except one, that is.
Inside Mount Weather, however, the boss realises that his minions are plotting. They do not care about his long-term plans for integrating the 100's radiation-resistant DNA into the gene pool. No, they care more about themselves than about future generations.
The Prez (Isaiah Washington - ) returns to base-camp and tells Clarke’s mom the news. Either they leave the forest and go to the desert, or they have to fight the barbarian Grounders. The Prez thinks they cannot win the fight: Clarke’s mom ( Paige Turco ) refuses to leave the 47 teenagers in Mount Weather.
Clarke tries to help Bellamy (Bob Morley - Road Train AKA Road Kill ) and Octavia ( Marie Avgeropoulos ) with Lincoln. Their knowledge of medicine is limited to say the least, as is their ability to safely incarcerate a criminally insane person. Can they cure Lincoln without killing him before he kills them? Nyko the medicine man (Ty Olssen - Supernatural ) lends a hand.
Inside Mount Weather, the Doctor discovers that mere blood transfusions are not enough. They will need bone marrow transplants. The entire 47 will be used as involuntary donors, with no survivors. Unfortunately, nobody remembers that even if the Mount Weather staff could live on the surface they would still be surrounded by thousands of angry stone-age barbarians.
Clarke tries to negotiate with the barbarians. The adults did not think it was worth bothering – no wonder this Young Adult show always puts the teenagers in charge!
Clarke delivers the Grounders’ demands. They want Finn, so they can execute him for accidentally massacring a village full of civilians. Councillor Kane (Henry Ian Cusick - Lost ) has another option – have Finn tried and punished by his own kind. But will the Grounders agree to it? Lincoln warns them that the Grounder leader would appear weak, inviting a coup.
Raven and Clarke both blame Murphy (Richard Harmon - Continuum ), although under the circumstances he is perhaps the sanest and most decent of the crew.
Raven has flashbacks to the incident that got Finn thrown in the brig. It explains why she is so dedicated to him. It also illustrates the obsessive lengths that Finn will go to for a girl he likes. Had Bellamy (Bob Morley - Road Train AKA Road Kill ) known this, would he have trusted him with a gun?
Raven blames Clarke for what happened to Finn. Worse, Clarke blames herself. She sees Finn’s image everywhere, haunting her. Her guilt paralyses her, and she refuses to let Bellamy (Bob Morley - Road Train AKA Road Kill ) attempt to infiltrate Mount Weather.
Nyko the medicine man (Ty Olssen - Supernatural ) and the Grounders take Finn to the village where the massacre happened, so he can be cremated with his victims. Clarke and a small delegation accompany the Grounder Commander, as part of the new alliance. But someone tries an assassination in order to disrupt the alliance.
Back in Mount Weather, the nerds work out a way to hack into the communications system. But can they do it without getting caught?
Clarke and the Grounder Princess try planning their next move, but Clarke’s plan is mostly to wait for Bellamy (Bob Morley - Road Train AKA Road Kill ) to work from the inside. The Grounder general is unhappy with this, and wants to kill Clarke. Things will never get better in this alliance if Clarke gets framed or shot at every single day. Worse, the bunker is right next door to an old zoo ... and one of the predatory exotic animals has thrived in the new forest environment. However, this is a great chance for her to bond with her opposite number.
Back at the camp, the Grounders and the Guardians start training together. It is more like parallel play, because the Grounders have superstitions against using guns and refuse to fight the Guardians hand-to-hand. Only Octavia ( Marie Avgeropoulos ) is willing to duel a grounder warrior, in the hope of earning their respect. This just makes it more apparent than ever that the teenage girl is actually played by an actress in her late twenties.
The Prez (Isaiah Washington - ) is the only one who expresses any doubts about the alliance. He reasons that as soon as Mount Weather is taken out, the Grounders will wipe out the Sky People too. He chooses Murphy (Richard Harmon - Continuum ) as an ally, because the Grounders blame Murph for Finn’s actions. Will Murph join the Prez on his next madcap scheme?
The Mountain Men have somehow learned that Clarke and the Grounder Princess have formed an alliance. They send a sniper and spotter out to assassinate the girls. Unfortunately for them, their radiation suits do not double as ghillie suits so they have no camouflage. The Sky People, with their blood fusions and duct tape, have the ability to take one of them alive.
First, Councillor Kane (Henry Ian Cusick - Lost ) the Security Boss proposes torturing the prisoner for info. Clarke and her mother ( Paige Turco ) oppose torture on both moral and practical grounds. Then Clarke has an about-face, and decides to murder the man. The Security Boss has to side with Clarke’s mommy, because the man is more useful alive than dead. Finally, in this game of moral musical chairs, Clarke arrives at a compromise. Unfortunately, she has a problem with mathematics. She does not realise that if someone has limited oxygen, if they run they will use up more oxygen than if they walked.
Bellamy (Bob Morley - Road Train AKA Road Kill ) is inside Mount Weather. He learns that they are not all military or scientific staff, and there is even a pre-school in the base.
The sniper that Clarke released tries to run the 24 miles (8 hours walk at 3mph) back to Mount Weather. However, since he uses oxygen faster when he runs ...
The villains’ blood-sucking leader can now walk in direct sunlight. Yes, he is now the equivalent of Klaus Mikaelson from The Originals . Except that he has no superhuman powers, and the only thing that makes him unusual is that he can accomplish the bare minimum that any normal Grounder or Sky Person can do. However, there are OTHER Mountain men who have taken the treatment. One of them is sniper-trained, with all the camouflage and concealment skills that the other two lacked. To counter the secret Grounder army that Clarke bluffed the POW with, they want to take out the conference of Grounder leaders. Also, instead of a sniper rifle they have decided to use a missile. A shoulder-launched SSM could take out a mud-hut full of Grounder VIPs, but the villains decide to use a medium-range ballistic missile.
Bellamy (Bob Morley - Road Train AKA Road Kill ) has the run of the mountain, blending in with the guards. He tells the wimpy kids that they should fight back, rather than get murdered one at a time. However, the kids were scary as a lynch mob when they attacked Murphy (Richard Harmon - Continuum ) last year but even when they outnumber the guards ten to one they are useless in a fight. The idea of killing the lady doctor, who is unarmed an unarmoured, never occurs to them.
Raven gets Bellamy to rig the Mountain transmitter to a walkie-talkie, and crawl in an air duct Die Hard style, so Clarke can hear the villain’s plans. She knows about the missile ... but saving the VIPs will blow Bellamy’s cover, and until he gets rid of the acid fog they cannot risk losing him.
Octavia ( Marie Avgeropoulos ) confronts Lincoln ...
Murph and the other runaways get mugged by a man with an RPG-7. Yes, an anti-tank weapon with a single shape charge against a well-spread-out group with guns. Will anyone have the brains to just shoot the guy?
Octavia ( Marie Avgeropoulos ) and the others try to dig the survivors out of the rubble. For a girl who spent her entire life under the floor or in a prison cell, she has become a real ninja! Paige Turco may be the new Prez, but she is also the only trained medical doctor on site. Except for Nyko the medicine man (Ty Olssen - Supernatural ), that is, but he does not really count. She goes into the unsafe ruins to save Thomas, and gets stuck there.
The spotter is still in the high ground, and gives his position away by using a sniper rifle against the survivors. But Clarke and the Grounder Princess are nearby, so they try to track him down.
Back in Mount Weather, the kids have barricaded themselves into the dorm. The villain sends in his riot squad, but the kids almost have a strategy. Luckily Bellamy (Bob Morley - Road Train AKA Road Kill ) is still wandering around in disguise. Also, there is a resistance movement led by Ian Tracey (the third actor re-used from Continuum , after Murphy/Theseus and Terry Chen).
Bellamy’s messing around saving the kids has backfired. The security team, using all the technology and learning at their disposal, have increased their security. He cannot get access to the acid fog projector.
Octavia ( Marie Avgeropoulos ) is not a fool, and has worked out how Clarke escaped the missile. It is amazing how quickly the girl who lived under the floor has become an expert warrior and an arrogant stroppy bitch. Will Octavia keep her mouth shut, or will Lexa the Grounder Princess shut it for her? We learn why Lexa cares for Clarke so much.
Murphy (Richard Harmon - Continuum ) and the half-dozen survivors stuck in the desert learn the hard way that they are stuck in a minefield. Strangely the mines are powerful enough to be anti-vehicle weapons (as opposed to toe-poppers that are used against infantry) but have such a low trigger setting that a man on foot can set them off.
The teens are being hidden by dissidents in the bunker complex. The evil overlord has a new policy to clamp down on the dissidents. This involves room-by-room searches, and summary execution of anyone found hiding the kids.
Raven and her engineer BF break into the hydro-electric dam and try to blow up the turbine generators. But they need to blow up all five in order for the plan to work. Meanwhile, Octavia ( Marie Avgeropoulos ) and a group of Grounders infiltrate the Reaper tunnels. They can cure the Reapers, but are the Grounders any more trustworthy?
There is one issue that has yet to be addressed. The massive grounder Army has one goal - the release of the Grounder prisoners and the ending of the blood treatments. But since the Mountain Men have access to the Sky People’s bone-marrow, the blood treatments are no longer necessary. It would cost them nothing to release the Grounder captives.
However, there is another issue: the only problem with the bone marrow is that there are not enough donors. It is surprising that the donation recipients recover from the operation so quickly, but that is not the problem. If the number of donors was greater than the number of recipients (i.e. if all Ark survivors provided a small amount of bone marrow) then the Mountain men would get what they wanted without further loss of life.
Raven and her BF have been captured and are next in line for the chopping block. Worse, Clarke’s mother ( Paige Turco ) and her band of Sky People are in enemy hands. They were last seen tending to the survivors at the grounder capital, Ton Dee See. The Mountain Men must have been patrolling at a great distance from their base, deep behind Grounder lines ... Or else the Sky people must have come to reinforce Clarke, and blundered into an ambush.
Clarke and her team are too few in number to shoot their way in. The Prez of the Mountain Men is too well-protected, and even if he were killed his replacement would continue his scheme. When Councillor Kane (Henry Ian Cusick - Lost ) offers the sensible route (non-lethal donations of bone marrow) will this be accepted? Will the nerd’s Mountain Girl friend get a blood donation to stave off radiation sickness? Will Clarke do the unthinkable, and wipe out the entire population of the complex? And what of the guards who have already taken the bone marrow treatment, and are thus immune to radiation sickness?
Elsewhere, former Prez Jaha (Isaiah Washington - ) and Murphy (Richard Harmon - Continuum ) run into further difficulties. They follow a drone out to sea, where they run into a mutated sea creature. How many lives of his followers will Jaha sacrifice?
Murphy (Richard Harmon - Continuum ) went exploring, and discovered a secret nuke-proof bomb shelter. It had three months worth of food in it, which is just as well because he gets locked inside. This gives the local Skynet time to brainwash former Prez Jaha (Isaiah Washington - ) ...
In the space of three months, Bellamy the Assassin (Bob Morley - Road Train AKA Road Kill ) has wised up and been promoted. He reports directly to Councillor Kane (Henry Ian Cusick - Lost ), and commands a military patrol that drives around in a cool-looking jeep. Jasper the nerd (Devon Bostick - Being Erica ) is on his team, despite being an alcoholic depressive. Octavia ( Marie Avgeropoulos ) is their scout, because she has a horse. Well, at least she does not have to worry about getting a constant fuel supply.
The Grounders have a bounty on Clarke, whom they now call Wanheda. In the space of three months, Clarke has gone walkabout, gone brunette and gone lesbian. Well, hopefully that will boost the ratings a bit. In the previous Season she expertly fended off the Commander's advances, but now she seems very keen to do what she previously considered unthinkable.
Murphy (Richard Harmon - Continuum ) joins former Prez Jaha (Isaiah Washington - ) on an insane quest. Well, in a post-Apocalyptic wasteland there is nothing better to do. They team up with the scavenger girl who robbed them in the desert last year. Yes, she knew a shortcut that would have saved them many lives. Also, she is still a kleptomaniac. However, Jaha has a secret - the City of Light is like the Cylon VR in Caprica !
Councillor Kane (Henry Ian Cusick - Lost ) and Bellamy (Bob Morley - Road Train AKA Road Kill ) lead a patrol to search for Clarke. The bad news is, they get ambushed. The good news is, they make new allies. The worse news is, the Ice Nation are on the march. This is the most barbaric tribe of Grounders so far, and they are taking advantage of the power vacuum now the Mountain Men are gone.
Jasper the nerd (Devon Bostick - Being Erica ) gets his check-up from Clarke’s mother ( Paige Turco ). Then Nyko the medicine man (Ty Olssen - Supernatural ) arrives, wounded by the Ice Nation and in desperate need of a blood transfusion. The only place they can get him patched up is in Mount Weather. This means risking the treaty with the Grounders, even if it is only to save one of their own.
Clarke is a guestage of Lexa. The plan is to exchange her for a treaty with the Sky People. Councillor Kane (Henry Ian Cusick - Lost ) and Clarke’s mother ( Paige Turco ) go to the Alliance's capital. This is not the remote village set of 'Ton D.C., it is a skyscraper about two hundred feet high. The metal structure supporting the weight has survived nuclear war as well as a hundred years of wear and tear. Presumably the elevators no longer work, so everyone must go up twenty flights of stairs to get to the council chamber.
Raven and Felix Gaeta ( BSG 2003 ) go to Mount Weather to loot some tech gear. Bellamy (Bob Morley - Road Train AKA Road Kill ) and Octavia ( Marie Avgeropoulos ) go along for security. They discover that the Ice Queen has sent an assassin to destroy the alliance. Will they get to the council chamber before everyone dies?
Lexa lets things boil over with the Ice Queen. Lexa fights her own battles, but the Ice Queen uses her own son as champion. The battle will be to the death - but whose death?
Clarke tries to take things into her own hands. What really matters is that she learns about the Grounders' selective monarchy. There is a reason the rulers are children - there is a special sub-species with black blood!
One of Sky Crew decides to lead a rebellion. His plan is to murder as many grounders as he can. Bellamy (Bob Morley - Road Train AKA Road Kill ) goes along with this genocidal plan.
To ratify the alliance with the Grounders, the Sky People hold an election. Unfortunately, the rebel leader is permitted to stand. If he wins the election, it does not matter if Lexa wins the duel or not. While the Sky Crew may seem more civilised than the Grounders, they are just more effective at getting what they want.
The new leader of Sky Crew is a genocidal idiot. He leads a half-dozen hardened killers to exterminate the friendly army sent to guard them. This will not end well for anyone.
Clarke tries to reason with Bellamy (Bob Morley - Road Train AKA Road Kill ). Unfortunately he blames her for leaving him in charge, with only her mother and Councillor Kane (Henry Ian Cusick - Lost ) to shoulder the burden of adult responsibility.
Former Prez Jaha (Isaiah Washington - ) arrives back at the Sky Crew camp. He is unwelcome in the new regime, but they let him preach his religion. Raven is still walking wounded, but she is a prime candidate for a religious conversion.
The Ice Kingdom send Clarke and Lexa a gift - the last of the Mountain men. This puts Clarke in a bit of a dilemma. She spent all of the previous episode preaching her new creed of blood must not have blood. Now she is confronted with a situation where she must deny herself revenge, or risk being revealed as a bloodthirsty hypocrite.
The Dictator of Sky Crew decides to invade some farmland nearby. The problem is that there are already farmers living there. The Dictator sends Bellamy (Bob Morley - Road Train AKA Road Kill ) and a murder-gang there to ethnically cleanse the Grounders.
The flashbacks are to the original Space Station Thirteen, AKA Polaris. Back on Unification Day, they were the one Station that held off on joining up. Now we get to see their side of things - they were afraid that their murderous AI would take over the entire Station!
Murphy (Richard Harmon - Continuum ) is still alive, but he is being interrogated by a madman who is obsessed with Polaris.
Lexa is keen to follow Clarke's lead, and since Clarke has switched to being exclusively lesbian relationships this Season they get to spend a lot of romantic time together. Lexa's head minion regards Clarke as being an inappropriate influence on the Commander. As always in Grounder politics, the first course of action is to assassinate one's opponent. And one way or another, TV shows never have long-term relationships.
The Dictator and Bellamy (Bob Morley - Road Train AKA Road Kill ) start to hunt for the Liberal in their midst.
The Dictator takes no responsibility for anything. He even blames Kane for handing Finn over to the Grounders. This ignores the fact that Finn was sentanced to be one of the Hundred with good reason.
Gaeta (Alessandro Juliana - BSG2003 ) is still in camp, as the blacksmith - or chief engineer, as he calls himself. He is loyal to Kane, and gets roped into a crazy plan. Is Kane stupid enough to fall for an obvious trap, or will he manage to make a great plan and then mess it up in a completely different (but utterly avoidable) way?
With the camp in political turmoil, Jaha (Isaiah Washington - ) sits on the sideline and obsesses about finding the Thirteenth Station. To do this he needs more brains plugged into the City of Light. Unfortunately the Dictator has confiscated the brain-tabs. Luckily, Raven and Jaha can induce Jasper the alcoholic (Devon Bostick - Being Erica ) into helping them.
Last episode saw the end of the show's lesbian subplot. Now the showrunner decides to placate the LBGT community by playing up the show's token man-on-man relationship. However, as with most TV shows this relationship is set for some rocky times.
Clarke and Murphy (Richard Harmon - Continuum ) are guest-ages in the Capital, until a new Commander is chosen. Lexa's death sentance for any Sky-crew found outside Arcadia obviously does not cover them. Or Octavia ( Marie Avgeropoulos ), who meets with Bellamy (Bob Morley - Road Train AKA Road Kill ) in an effort to save Arcadia.
The succession is not primogeniture or democratic election. No, it is trial by combat! However, that does not make it a fair fight. The candidates are all children, and the eldest is a girl raised by the Ice Nation. Yes, the old Ice Queen is dead but a far worse one might soon take her place.
The dictator of Arcadia has sentenced Councillor Kane (Henry Ian Cusick - Lost ), Gaeta (Alessandro Juliana - BSG2003 ) and Lincoln to death. Clarke’s mother ( Paige Turco ) pops up briefly to say goodbye. A small band of recurring characters have a desperate plan to rescue them. This is basically a rerun of what happened in Mount Weather in Season Two!
Octavia ( Marie Avgeropoulos ) blames Bellamy (Bob Morley - Road Train AKA Road Kill ) for the events in the previous episode. Councillor Kane (Henry Ian Cusick - Lost ) and his group are hiding out in a cave, trapped between the fascists of Sky Crew and the bloodthirsty grounder blockade. Monty tries to join them, but it could be a trap.
The dictator of Sky Crew intended to turn Arcadia into a police state. However, he has wasted time by concentrating on Kane and allowing Jaha (Isaiah Washington - ) to peddle his religion. Raven is trying to block out the woman in the red dress by reciting a certain poem by Edgar Allen Poe. She also gets Clarke's mother ( Paige Turco ) and Jasper the alcoholic (Devon Bostick - Being Erica ) to help. Can she destroy the brainwashing chips before they turn everyone into zombies?
Back at the Capital, the new Commander keeps Murphy (Richard Harmon - Continuum ) as her pet. She chains him to a wall, and forces him to watch as she takes long bubble-baths. In return, he helps her bluff at politics instead of just killing everyone.
Clarke and Jasper the nerd (Devon Bostick - Being Erica ) take Raven to the other survivors. They decide to build the EMP and cure her. However, they do not bother to gag or blindfold her. As a result she constantly plays mind-games with them.
Octavia ( Marie Avgeropoulos ) blames Bellamy (Bob Morley - Road Train AKA Road Kill ) for the death of her lover. Jasper blames Clarke for the death of his lover. The Grounder girl blames Bellamy for the death of her father. Lots of blame for Raven to throw around.
Monty's mother tried to sell him out to Pike the Dictator. Now she is a henchwoman of the brainwashing AI. It certainly seems like her life expectancy is not getting any higher. Will our heroes kill her or cure her?
Clarke and the others return to the main camp. Everyone seems to have abandoned the place, so all the tech is there for the taking. However, someone else is stalking the group. He wants to take revenge on Clarke and all her friends.
Murphy (Richard Harmon - Continuum ) is enjoying life as the Queen's slave. Then he meets his previous girlfriend in the marketplace, and shows her a lot more trust than he would have a few weeks ago. Later, Jaha (Isaiah Washington - ) shows up. How Jaha got there from the main camp, with still no sign of Chancellor Kane, is not explained.
Clarke takes the others to the most remote corner of Lincoln's map. Hopefully they will meet the final nightblood there.
Councillor Kane (Henry Ian Cusick - Lost ) and the execution party arrive at the Grounder capital. They must have taken the scenic route, because Jaha's army has beaten them there. The mass-murderer is thrown in prison with Murphy (Richard Harmon - Continuum ) and Indra. How ironic that it is Kane himself who ends up getting the torturous punishment.
The flashbacks are to the day before the Hundred were sent to Earth. The mass-murderer was recruited by Jaha (Isaiah Washington - ) and Kane to give the Hundred a refresher course in survival skills. Murphy was a poor student, and Octavia ( Marie Avgeropoulos ) was the only one in the class who paid attention. This seems to be a bit of retro-fitting, to explain the complete disparity in their survival skills.
Murphy (Richard Harmon - Continuum ) and the prisoners stage their escape attempt. The bad news is, they are stuck at the centre of the enemy capital. The good news is, the temple with the AI's tech is nearby.
Raven discovers a backdoor into the City of light. She tries to hack the system. Despite being unaware of each others actions, if she and Murphy act simultaneously then they will destroy the AI.
Clarke and her team try to persuade the last Nightblood to become the new Commander. Unfortunately the girl is unwilling to take on the responsibility. Luckily she is also resistant to waterboarding.
Clarke has only one plan left - return to the Grounder capital and cure the Queen. Unfortunately, she does not know that one of her crew has been chipped. It could be Raven, who was supposedly cured, but both Jasper (Devon Bostick - Being Erica ) and his sidekick Monty have been moody since their loved ones died.
The Grounder capital is sparsely populated, so presumably the people have dispersed among the villages to spread the AI like a plague. Their HQ building has a functioning elevator, but the bad news is its winch is manually operated.
A couple of episodes ago, Kane was extorted by a threat to Clarke's mother. Ironic that Clarke herself is now tortured by her mother. Worse, she is herself extorted by a threat to the mother that tortured her. Will Clarke show the same weakness that Kane did? After all, if Kane had held out then he would look like a villain but in the long run he would have prevented Clarke's suffering.
Clarke takes it upon herself to put the Flame Chip in her head. The good news is, it can protect her from the AI while she searches for the kill-switch. The bad news is, it will only work while she has black blood pumped into her system. The good news is, she can now communicate with the former Commanders - so she can see her lost lover Lexa one more time. This is just fan-service for the hard-core lesbian fans who were so upset that Lexa got written out of the show. Well, Octavia ( Marie Avgeropoulos ) and Lincoln did not get their happy-ever-after ending, any more than Raven and Finn did in the previous Season. Even poor Jasper (Devon Bostick - Being Erica ) is in so much emotional turmoil that he wanted an AI to brainwash his pain away.
Meanwhile, the tower is under siege. The survival of the human race depends upon Octavia and the mad dictator working together. Well, there would be no drama without conflict, and no suspense without the inevitability of everything going wrong at the worst possible moment.
The city is in turmoil because of the end of the City of Light. The Ice Nation decide to take over, and are willing to kill anyone who gets in their way. This means besieging Sky Crew and Tree Crew.
Back at Arcadia, the Asian boy has gotten over his mother's death thanks to getting lots of sex with his hot blonde girlfriend. However, Raven is still grieving and crippled, and Jasper (Devon Bostick - Being Erica ) is still suicidal over the loss of his girlfriend. Meanwhile, Clarke and Octavia ( Marie Avgeropoulos ) are still grieving over the loss of their own lovers. Yes, teen angst all round.
The Ice Nation's King, Ronan ( Agents of SHIELD: S4 ), is on his deathbed. Command is now held by the leader of the Royal Guard. Like all the greatest warriors in this show, she is a beautiful young woman. Perhaps things would be better if they learned more mature arts like diplomacy, negotiation and compromise. The best solution would be one of marriages between the crews. After all, they will never trust each other - but perhaps the next generation will learn to live in peace.
The AI's exposition at the end of the previous Season is confirmed. The remaining nuclear power plants around the world are going to overload. In six months time, there will be another armageddon. The adults are useless, so only the tweenagers will be able to save the world.
The peasants still blame Sky Crew for what the City of Light did. Clarke's policy of blood must not have blood is ignored. One of the ambassadors wants to challenge King Ronan ( Agents of SHIELD: S4 ) to single combat. This is very well timed, because Roan is still recovering from having a bullet extracted from his chest. Councillor Kane (Henry Ian Cusick - Lost ) tries to negotiate a solution, but Octavia ( Marie Avgeropoulos ) prefers a more direct approach.
Clarke and Raven try to save Sky Crew. Their plan is to repair the Ark and use it as a shelter. Unfortunately there is only enough room for Sky Crew, which means that the other twelve tribes will be sacrificed. Jaha (Isaiah Washington - ) offers to help, but everyone still blames him for everything that went wrong. They ignore the fact that Clarke's mother was just as guilty.
Bellamy and a handful of youngsters go to Ice Nation to scavenge a hydro generator that will provide water for the population. Unfortunately the Ice Nation did not execute their Sky Crew prisoners, and instead have allowed some to live as slaves. The smart thing to do would be to take the generator home, then get king Roan to order the release of the slaves. The other choice is to start a war with the Ice Nation in order to free a couple of dozen extra mouths to feed a few days before they would be released anyway. Not much choice at all, really.
The ark only has room for a hundred survivors, which means the other four hundred people must be abandoned. As defacto leader, Clarke has been tasked with writing the list. However, she is reluctant to do so. Jaha (Isaiah Washington - ) has found a potential safe haven. A prophetic cult-leader (John Pyper-Ferguson - Alphas ) built a survival bunker for his cult. But how come nobody has heard of them before? Are they the ancestors of the Grounders, or are them the new Mount Weather?
Some Grounders arrive at Arcadia in need of medical attention. They are from the oil rig in the previous Season. The fish have started to die, killed off by radiation poisoning. This means the apocalypse will happen in two months time, instead of the six months that the AI had predicted. Raven does not want to waste valuable medication on dying children. Murphy (Richard Harmon - Continuum ), ever the survivor, drops by to help out.
King Ronan ( Agents of SHIELD: S4 ) sends Octavia ( Marie Avgeropoulos ) to find the magic Super-AI tablet. It has been stolen by a fanatical priestess, and may fall into the hands of the neo-Luddites who want to destroy all technology so the City of Light cannot rise again. Roan wants to prevent a civil war, but Octavia is an enthusiastic killer who would probably welcome such a war.
Jasper hangs around playing practical jokes while everyone else is working to build a super shelter. Unfortunately he discovers the supposedly secret list she created last week. Do the workers have the right to know that their fate has been decided by a teenage girl? After all, as she freely admits her only authority comes from the fact that she is Kane's proxy. Luckily Jaha (Isaiah Washington - ) is still around, helping out as an engineer.
Councillor Kane (Henry Ian Cusick - Lost ) tries to persuade Octavia ( Marie Avgeropoulos ) not to go around killing people all the time. However, he has bigger problems to worry about. Clarke and Bellamy broke the treaty with King Roan ( Agents of SHIELD: Season 4 ). After all, Sky Crew have spent the last two weeks working to protect themselves - well, one in five of them.
Clarke's mother leads another expedition, this one to the island where the AI was hiding. Murphy (Richard Harmon - Continuum ) and his girlfriend come along as guides. The AI may be gone, but somehow the security drones are still active. Worse, Mama has brought the only black-blood with her. If the black-blood dies, they will have no source of blood to clone.
Octavia ( Marie Avgeropoulos ) gets found by the anti-technology obsessive, who gets her to Arkadia so she can warn her friends. Clarke takes a handful of sharpshooters to ambush the Ice Nation army. Her plan is to negotiate another peace treaty with King Ronan ( Agents of SHIELD: S4 ). Unfortunately, one of her minions has other ideas. He was a slave of the Ice Nation, and like all tweenagers he cares more about revenge for being forced to do chores than he does about safeguarding the future of the human race.
Clarke's mother has locked herself in the bunker with Raven and another tech. The good news is, they make incredible progress. The bad news is, it is linked to the after-effects of the AI chip from the previous Season. Worse, the long-term effects may include fatal brain damage.
Clarke's mother is nowhere in sight this week. She delegates the piloting simulation to Raven, and in turn Raven's welfare is delegated to Murphy (Richard Harmon - Continuum ).
Clarke and Bellamy (Bob Morley - Road Train AKA Road Kill ) take their last remaining barrels of rocket fuel to the island. King Ronan ( Agents of SHIELD: S4 ) and his bodyguards come along to help. Unfortunately, since Ice Nation and Tree Crew are at war the roads are not safe and they inevitably run into trouble.
The token adult, Chancellor Kane (Henry Ian Cusick - Lost ), tries to keep the law in the ruins of Arkadia. Octavia ( Marie Avgeropoulos ) is still recovering from her injuries, and is in no mental or physical state to back him up.
The black rain starts to fall. The token adult, Chancellor Kane (Henry Ian Cusick - Lost ), tries to keep the law in the ruins of Arkadia. Bellamy (Bob Morley - Road Train AKA Road Kill ) goes out in a jeep to round up stragglers. One of them is Octavia ( Marie Avgeropoulos ), who went walkabout in the forest.
Clarke makes it to the island. Her mother has a potential cure, but she is at the human testing phase. They need a subject that they can expose to lethal levels of radiation, but the only expendable personnel are Murphy (Richard Harmon - Continuum ) and his scavenger girlfriend. By incredible coincidence, another scavenger breaks in. Is he a starving loner who has not eaten in days and merely wants food and shelter from the black rain? Or is he a murderer obsessed with killing Clarke's friends? Well, when is the last time Clarke actually met someone nice?
Clarke and her friends have taken the nightblood to the human testing phase. They do not bother with animal testing, or to request volunteers. Murphy (Richard Harmon - Continuum ) and his girlfriend are deemed expendable. The only one who objects is Raven. Will Clarke become as bad as the Mount Weather crew?
Jaha (Isaiah Washington - ) discovers a clue to the true location of the bunker they looked for in The 100 [Season 4, Episode 3] The Four Horsemen. He goes back to the Capital in order to speak to the priestess. Chancellor Kane (Henry Ian Cusick - Lost ) abandons his position as leader of Arkadia, and tags along on the mission. Unfortunately, Tree Crew is still at war with the Ice Nation.
Bellamy (Bob Morley - Road Train AKA Road Kill ) reluctantly accompanies Jasper to a rave party in the woods. Since they are all about to die, their motto is now to do whatever the hell we want.
