This is set in the same cinematic universe as Marvel's X-Men . Mutants are feared and despised. The famous ones have disappeared, and the minor ones are hunted by the police. The LAPD only have conventional weapons like pistols and tasers, while the mutants have telekinesis to manipulate matter or energy. Yes, the police are sorely out-classed when it comes to a fight.
Reed Strucker (Stephen Moyer - True Blood ) is a Government prosecutor who specialises in cases concerning mutants. He and his wife, Caitlin Strucker ( Amy Acker ), are worried that their son is being bullied at school. As a result they put him on lockdown at home.
Strucker Junior sneaks out with his sister. They go to the school dance, held in the school gymnasium. It turns out that the Strucker children have mutant powers. He gets attacked by the bullies, and the result is like something out of Carrie (albeit toned down for television).
The family must go on the run from the government. The Sentinel Service is on their tail. It is not a group of indestructible killer robots like in X-Men: Days of Future Past , it is just a group of Federal agents led by Jesse from Burn Notice. Let us bear in mind that the mutant underground, a well-organised group of mutant people-smugglers, is left to the poorly-equipped LAPD. Why are the Struckers the only ones of interest to the Feds?
Clarice "Blink" Fong ( Jamie Chung ) is in a feverish state, and opens portals uncontrollably. Nobody thinks to render her fully unconscious. The police investigate the portal, and try to send a SWAT team in to raid the Mutant Underground HQ. Well, they send in one man who is unsupported. So much for teamwork.
Caitlin Strucker ( Amy Acker ) agrees to help the Mutant Underground steal medicine from a hospital. The doctor assumes she is the victim of domestic violence. The subtext of this is that the Mutant Underground Army fights oppression the same way that Mens' Rights Activists do.
Reed Strucker (Stephen Moyer - True Blood ) is in Sentinel custody. They even pull in his mother ( ) for questioning too. Meanwhile, a much more valuable prisoner - MRA leader Lorna "Polaris" Dane ( Emma Dumont ) - is left in LAPD custody. They have put a special collar on her, and thrown her into gen-pop. Since the other inmates are violently prejudiced against mutants she might not live long enough to sit trial, never mind provide the Sentinels with valuable info.
Caitlin Strucker ( Amy Acker ) takes her teenagers to hide out at her brother's house. Unfortunately the whole family are civilians and have no idea of how to keep a low profile. It is only a matter of time before someone screws up and gets them all caught. The good news is, instead of having to dodge a highly-trained Sentinel SWAT team all they have to worry about is every shotgun-toting redneck in the suburbs.
Clarice "Blink" Fong ( Jamie Chung ) has lost her mojo since she was ill last week. Can she master her powers again in time to save the day?
Reed Strucker (Stephen Moyer - True Blood ) and MRA leader Lorna "Polaris" Dane ( Emma Dumont ) are about to be transferred to a more secure prison. Can the Mutant Underground get their act together and stage a rescue?
Unfortunately the Mutant Underground rely on their superpowers. They have little to nothing in terms of weapons and tactics, especially compared to the Feds' SWAT (Special Weapons And Tactics) team.
The Feds set up a bunch of road blocks to keep the rebels penned into the city. Their next step will be to start searching the area. They will never stop, until they find the rebel HQ.
Torch (Oscar Isaac - Star Wars: The Force Awakens ) and his girlfriend get stopped at a Fed roadblock. The Feds have realistic-looking costumes, props and tactics. However, they are no match for a girl with telekinetic superpowers. Jessie gets taken hostage by the very woman he held prisoner in the previous episode. She calls in her telepathic friend to read his memories. However, messing with a person's memory can cause them severe issues.
Reed Strucker (Stephen Moyer - True Blood ) volunteers to act as a decoy and lead off the cops. He does not really have much choice. The getaway driver recognised him from the time he admitted to wearing a wire for the Feds, and has ungratefully tried to rile the other mutants up against him.
The Mutant Underground go on the offensive. Their target is a government building in Baton Rouge. Reed Strucker (Stephen Moyer - True Blood ) goes along, because he is the only one who knows much about the system. His son goes along, because his superpower can be useful for breaking through walls.
The Mutant Underground HQ is full to 78% over-capacity. The good news is, this means new foot-soldiers for the Mutant Underground. The bad news is, the mutant family members tend to be teenagers rather than adults. Caitlin ( Amy Acker ) objects to her children being recruited as child soldiers in the Mutant Underground. However, they are high-powered mutants and should be trained to defend themselves. After all, the government will be after them even if they leave the Mutant Underground.
The teenage daughter makes a new friend, a fellow teenage recruit into the Mutant Underground. He is set up as her potential love interest. By an incredible stroke of luck, his superpower is just the one that they will need in the episode's climax.
The Feds have re-doubled their efforts to find the Mutant Underground. Dr Campbell (Garrett Dillahunt - Sarah Connor Chronicles ) has a plan to deploy extra assets. They take the view that the Mutants are not just terrorists but seperatists, not merely from the US government but from the human species. In other words, the Feds' line about removing civil rights from suspected terrorists is compared the the historical Dred Scott decision by SCOTUS that removed human rights from all African-Americans - even the free ones!
Reed Strucker (Stephen Moyer - True Blood ) goes through the Feds' files, and discovers that his daughter's boyfriend has a criminal record. He acts like an over-controlling psycho-dad, as if they were still living a happy life in the suburbs. It turns out that the young man was once homeless, because his family kicked him out when he turned out to be a mutant, and he had to steal food in order to eat. Well, he joined a street-gang and perhaps stole some luxury goods instead. But the principle is the same - he lived the Oliver Twist lifestyle, and the rich suburbanites judge him over it.
Torch (Oscar Isaac - Star Wars: The Force Awakens ) gets called in by his ex-GF, the gangster. She wants him to help destroy a rival gang's drug shipment. Her motive is to increase her own profits, but Torch has an anti-drug agenda so he should consider this a good thing.
Torch (Oscar Isaac - Star Wars: The Force Awakens ) and his team go to pick up another batch of refugees. One is a telepath, and she warns them about a potential threat.
The ex-DA Reed Strucker (Stephen Moyer - True Blood ) pays his estranged father a visit. The old man does not know much about Trask Industries, because it was originally shut down many years ago. However, he knows a lot about the DA's family tree. The twins are not the first mutants in the family.
Caitlin Strucker ( Amy Acker ), as the only Doctor in the mutant HQ, helps deprogramme one of Dr Campbell's mutants.
Reed Strucker (Stephen Moyer - True Blood ) updates his wife Caitlin ( Amy Acker ) on what he discovered about their children. By working together, the kids can amplify their powers and destroy an entire building. The Mutant Underground know about this too, and they plan to use the kids as a weapon on their next mission.
Dr Campbell (Garrett Dillahunt - Sarah Connor Chronicles ) was badly burned in the previous episode. He refuses surgery, and instead relies on his mutant sidekick to heal him.
Jesse from Burn Notice realises that the mutants will go on the offensive. The next logical step is for them to attack Trask Industries HQ, to free all their friends who are imprisoned there. However, Trask is so secret that even the Feds do not know where the HQ is. Can he find it before the mutants break in?
This starts with a flashback, two months previously. A Trump-type politician complains about low turnout at his hate rally. His familiar-looking blonde intern tries to ingratiate herself with her boss, although she seems unhappy about being referred to as Hon. Then the anti-mutant cops turn up ...
Back in the main timeline, the Strucker kids are in the custody of Dr Campbell (Garrett Dillahunt - Sarah Connor Chronicles ). He wants them to combine their powers, so he can test their Fenris superpower.
Reed Strucker (Stephen Moyer - True Blood ) and his wife Caitlin ( Amy Acker ) go after Sentinel Services Agent Jace Turner (Coby Bell - Burn Notice). If they convince him to do his duty, he will transfer Trask's mutants into Federal custody. After all, if they are really criminals then they deserve due process and a fair trial.
The blonde girl who joined the Mutant Underground a few episodes back has a plan for attacking Trask Industries. There are a lot of guards there, but they soon learn what the SWAT teams learned in Extant . Mundane humans are incredibly vulnerable to inception by Teeps, and firearms are a force multiplier to that.
The Mutant Underground hold a private remembrance ceremony for the member who was killed in the previous episode. Meanwhile, Jesse from Burn Notice does the same. His partner was killed, and he wants payback. He views the mutants as fallen angels, people corrupted by their own power. Dr Campbell (Garrett Dillahunt - Sarah Connor Chronicles ) offers a team-up, using the next level of anti-mutant tech.
There are now three blonde girls - the Frost triplets. If they look familiar, they were the boring girl Grace in Scream Queens . Now that they are evil, they seem much hotter. They report back to their master. It turns out they are trying to re-build the Hellfire Club, the villains from X-Men: First Class . They return to the Mutant Underground, and request backup on their next mission. This causes the leaders to debate their morality. Torch (Oscar Isaac - Star Wars: The Force Awakens ) does not want to team up with a terrorist group - if he was so easily led, he would just have stayed with his ex the gangster.
Reed Strucker (Stephen Moyer - True Blood ) and his wife Caitlin ( Amy Acker ) are unhappy at the way things are going. They choose to go to safety in Mexico, and get shipped off to a safe-house elsewhere.
Campbell takes Jesse on a mission, to demonstrate his new tech. Naturally this involves a big battle with the other main characters. The terrible triplets just happen to be in the right place at the right time. Nobody seems to realise that they probably set it all up so they could seem like saviours to the mutants.
Dr Campbell (Garrett Dillahunt - Sarah Connor Chronicles ) attends a conference for rich and powerful anti-mutant types. The Frost sisters have a plan to gate-crash it, and they bring the Mutant Underground along for muscle.
Reed Strucker (Stephen Moyer - True Blood ) has to get to his mother ( Sharon Gless ) before the Feds do. He and his wife Caitlin ( Amy Acker ) bring the kids for backup. Unfortunately Randy has begun to get a bit bloodthirsty.
This is the second part of the two-part Season finale. Dr Campbell (Garrett Dillahunt - Sarah Connor Chronicles ) has won more support, as the victim of a mutant attack. Now it looks like he will get the political concessions he requested.
Randy admires the Frost sisters, and not just because they are hot. They have embraced their mother's heritage as super-villains. He wants to bring back the Von Struckers. Nobody has ever told him that it was a bad thing to be a Nazi war crimninal!
Sentinel Servives closes in on the Mutant HQ. He has the tame mutants that Campbell brainwashed, plus a full SWAT team with an armoured truck. In contrast, all the main mutants are off on a mission. Luckily, Reed Strucker (Stephen Moyer - True Blood ) gets a defence cobbled together while Caitlin ( Amy Acker ) gets the mutants to create an escape tunnel.
At the end, the Mutants have a choice. Will they stick with the Struckers, who saved everyone ... or will they join the Hellfire Club, who are to blame for all the trouble in recent episodes?
