High in the Santa Monica Mountains grisly murders are taking place. On each of the victim's bodies a note is left for L. A. Sheriff's detective, Gabriel McRay. The killer's identity is locked in the suppressed memory of a horrifying trauma from Gabriel's own childhood. 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.
