When an office worker receives a photograph of a grisly murder scene, he thinks it's a prank, not the start of a killing spree where he knows each and every victim. Nigel Randolph, a solitary man with a history of mental health problems, is implicated in a macabre set of killings, drawn into a dark world of subterfuge and deception, which leaves him questioning his own sanity. As the police investigation progresses, Randolph discovers evidence of radical hypnotherapy sessions, that he may have been experimented upon as a child, and is now victim of a high-level cover-up. Only if he can piece together what happened to him during the controversial psychiatric treatment of his youth, will he ever find out the truth.
