Detective Caitlin Hendrix is pulled back into a nightmare that previously destroyed her father, Mack, when he was a detective twenty years earlier. Mack was on the case of a serial killer known as the Prophet. The Prophet played mind games with him and was never caught, eventually destroying Mack's career. Now either the Prophet is back or there's a very good copycat in action. Caitlin is determined to overcome his psychological games, decipher his twisted messages and keep him from killing again despite her father's warnings.
