Troubled detective Gabriel McRay is fired for police brutality. When a killer begins leaving notes on his victim's bodies addressed to the detective, Gabriel is hired back to lure in the killer. Gabriel's troubles stem from the blocked memory of childhood trauma. With his career dependent on the whims of a psychopath, Gabriel soon realizes that the killer's identity lies within that blocked memory. Teamed with his forensic pathologist girlfriend and his psychiatrist, Gabriel runs two parallel investigations. The first: a dark journey into the terrifying recollections of his past and the second: the hunt for a serial killer who seems to know more about Gabriel... than he knows himself.
