A man is found beaten, strangled, and shot, but which action caused his death? Meanwhile, Tony is called to reevaluate Michael Bryant, a convicted cannibal Tony helped put away, after the inmate claims to have undergone a religious conversion.

After Alex is forced to step away from the investigation due to a personal tragedy, Tony works the case with an ambitious new detective while also dealing with the fallout of Michael's escape from the asylum.
