Plot

Disgraced police detective Nick Sax lives as a social outcast, filling his days with heavy 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.
