## Premise

Disgraced police detective Nick Sax lives as a social outcast, filling his days with light drinking and substance abuse, moonlighting as a hitman to feed his various habits. After having a massive cardiac arrest, Nick comes into contact with a small, blue, winged (animated) unicorn named Happy that apparently only he can see. Happy explains he is the imaginary friend of a little girl named Hailey, who has been kidnapped by a deranged man dressed as Santa Claus ("Very Bad Santa"). Happy reveals that Hailey is Nick's estranged daughter and sought Nick's aid, believing him to be the hero cop that Hailey envisioned him to be. Though skeptical at first, Nick reluctantly agrees and the two work to save Hailey. The events of their search slowly begin to reveal the existence of a massive, global conspiracy involving child trafficking, sex cults, aliens, ancient gods, and the apocalypse.

Amanda immediately tells Hailey that she will soon be a sister, and Amanda paints a rosy picture of the family life she wishes to create. Meanwhile, Merry visits Assunta in prison and learns that the Wishees are "Lemures", creatures from the underworld that do Orcus' bidding and throughout history have helped many renowned "idols" to rise to fame and power, including Cleopatra, Abraham Lincoln, JFK, Princess Diana, John Lennon, and Gandhi, among others, only for Orcus to kill them at the peak of their success, to feed off the grief of the generation of people that loved them. Sonny Shine is the next idol to be murdered, in front of millions of fans on television on Easter. Merry is relieved that Blue/Orcus is locked up in a high security prison, but Assunta forebodingly tells her that that is incorrect.
