Jason is an agent that destroyed his career and his family years ago obsessed to capture a serial killer; now the leads indicate that the same killer has just started a new crime spree. Soon the psychiatrist Dr. Alyce Robertson receives phone calls from the killer and she meets Abraham that asks her to talk to Jason. He asks to participate in a meeting with her patients William Frost; the agoraphobic Rachel Quinn; Gail Morgan; Jerry Saracen; and Eileen Gibbs.
