The series is executive produced by Morrison and Brian Taylor, who wrote the pilot together. Neal Moritz, Pavun Shetty and Toby Jaffe of Original Film will executive produce alongside Meloni and showrunner Patrick Macmanus. Taylor directed the pilot, which airs in December. The first season will run for eight episodes, and sees a former cop team with an imaginary horse -- read the official synopsis below for the full rundown.

"The series follows Nick Sax – 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.'"
