When two dismembered and unidentifiable torsos wash up on a local riverbank, nurse Caroline Reeves, believes the killer is a man from her past with a history of mental problems. She contacts FBI Special Agent Walker Harmon, who arrives to the sleepy town of Pleasant Valley, and met with a reception of lies and threats from local police and citizens. Under constant pressure from both the media and public, along with taunting messages aimed at him and Caroline from person's unknown, the agent races against time to catch the killer before he strikes again, and before an innocent man is convicted. With a suspect list involving the victim's parents, ex-lovers, Satanists, corrupt police, and the motorcycle gang the Devil's Disciples, circumstances turn the hunt personal, as the hunters become the prey.
