[Season 1 !Season 2 !Season 3 ]
Lucifer Morningstar (Tom Ellis - Merlin ) has quit his job as Prince of Hell and is now owner/manager of a night club in Los Angeles. His sidekick, Maze ( Lesley-Ann Brandt ), is a demon posing as a bartender.
A rival angel, Amenadiel (D.B. Woodside - Buffy: Season 7 ), drops by to remind Lucifer of his responsibilities. However, he would rather hang out with his former employee Delilah ( Kayla Ewell ). She did not have to sell her soul to become a celebrity, because Lucifer gave it all to her for free.
Lucifer decides to play detective. The LAPD officer in charge of the case is Chloe Decker ( Lauren German ), and ironically her ex-husband Dan (Kevin Alejandro - Arrow: Season 2 ) is a cow-orker of hers.
Lucifer's superpowers seem limited. He can recover instantly from a hail of bullets, and escape with ease from a pair of handcuffs. However, he cannot read minds or uncover sins - merely persuade people to tell him their deepest desires. Also, he is willing to prostitute himself to women, providing sexual favours in exchange for information. If only women were treated as equal to men, and thus behaved with equal sexual availability.
Lucifer Morningstar (Tom Ellis - Merlin ) is still prostituting himself to Dr. Linda Martin ( Rachael Harris ) in exchange for psychiatric advice. LAPD Detective Chloe Decker ( Lauren German ) is still interested in solving the mystery of how Lucifer is bulletproof. Neither of them believe him when he confesses that he is the Dveil.
Lucifer is obsessed with Chloe too. He accompanies her to a crime scene, and they both involve themselves in a police investigation. The actual investigating officer is Dan (Kevin Alejandro - Arrow: Season 2 ), and neither Lucifer nor Chloe is allowed to be involved with the case. Of course, this will not prevent them.
A paparazzo (Jeremy Davies - Lost ) has confessed to causing a car crash in a Princess Diana type pursuit. Chloe has a grudge against him from her earlier days as an actress. However, she takes it upon herself to clear the man's name and find the real killer.
Amenadiel (D.B. Woodside - Buffy: Season 7 ) reveals that Lucifer's stay among mortals has weakened him. He has begun to show empathy towards victims.
Lucifer is portrayed as a likeable rogue because of his sex-positive attitude. Unfortunately the reactionary TV network that this show is made for is not the kind to tolerate a similar attitude from the female protagonist. Chloe's backstory is that she was an actress when she was younger, and became famous for an amazing topless scene. However, she is portrayed as a victim whose life was ruined and may have problems raising her child because of her on-screen nudity. The real slut-shaming is aimed at the paparazzos (and their audience), who are obsessed with nip slips and upskirt shots.
Lucifer's powers are inconsistent, a problem prevalent in superpower stories. They allow him to abduct a suspect from police custody, but he can only get a confession from the suspect when the plot demands it. Despite being an archangel he cannot slow time, although a lesser angel like Amenadiel can do it. Finally, he complains that sinners will not be punished in the afterlife so he takes it upon himself to do in on Earth instead. Surely this is what the police, courts and prisons are for. Hell is therefore unnecessary duplication of the American justice system.
