Thomas Horton was a good cop. Faced with early retirement as a result of his affiliation with the secretive and sometimes violent vigilante named Xander Drew, he tries to settle into civilian life: but there remain three unsolved cases from when he was on active duty. The facts of these three unsolved cases still keep him up at night. Now in the short time since he left his position, one of the killers he could not catch has resurfaced: a serial killer who flaunts his sinister intent in front of the Los Angeles Police Department for all to see, making it so that no one is safe. Unable to convince the rest of the LAPD of the connections between the two cases, Horton must again ally himself with Xander Drew, entering in a game of quid-pro quo in exchange for information about a dangerous ganglord. Without the badge to shield him, can Horton’s moral certainty survive another encounter with Xander?
