 A forensic psychologist, Sally Rowe, is appointed by police to determine whether there s enough evidence to lay murder charges against 17 year old Alex, accused in the shotgun death of his school mate Nigel. With no tangible evidence, the detective on the case is under pressure from Alex s influential father to have the charges dropped. Delving deeply into Alex and Nigel s bizarre symbiotic pact, Rowe discovers that though dead, Nigel s psychological effect on Alex is far from diminished.
