“Happy!” is based on New York Times best-selling author Grant Morrison and Darick Robertson’s graphic novel of the same name. The series follows Nick Sax (Christopher Meloni, “Law & Order: SVU”) – an intoxicated, corrupt ex-cop turned hitman – who is adrift in a world of casual murder, soulless sex and betrayal.

After a hit gone wrong, his inebriated life is forever changed by a tiny, relentlessly positive, imaginary blue winged horse named Happy (Patton Oswalt). Season 2 begins with Easter on the horizon –a season of hideous pastels, dye-stained fingertips and a general “who really gives a f***” attitude.

A newly sober-ish Sax finds himself struggling with the demands of family and fatherhood. He has sworn to do right by his ex-wife, Amanda, and his daughter, Hailey, which means no booze, sex, drugs or killing. Happy, meanwhile, is resigned to keeping his partner on the straight and narrow while coping with the fact that a maturing Hailey can no longer see him.

Sax’s fresh start will be tested by a familiar enemy: Sonny Shine, who is on a mission to Make Easter Great Again (MEGA) with the help of his demented Easter Bunny henchman.

“Happy!” is produced by UCP (Universal Content Productions). Executive producers include Morrison (“Batman,” “The Invisibles”), Brian Taylor (“Crank,” “Gamer”), Neal Moritz, Pavun Shetty and Toby Jaffe of Original Film (“The Fast and the Furious” franchise), Meloni and showrunner Patrick Macmanus.
