 Jason Enola is an obsessive FBI agent who is almost losing his mind after ten years on the tail of an elusive serial killer whose hallmark is the "paper trail" of notes left along with the victims. Brad Abraham is the agent buddy who is watching Enola s back. As the film begins, a new wave of killings start after four years of silence, and the psychiatrist Dr. Alyce Robertson becomes involved when she starts receiving telephone calls from the killer.
