After 5 months undercover, Murphy finds himself looking over his shoulder when the arms dealer he had befriended, Nikolai, gets away. He subsequently ransacks Murphy's apartment looking for revenge. The police now investigate two very similar deaths. Both victims were male, quite rich and were at the same health club the day they were killed. They were drugged and a woman's blond hairs are found at the scene. Murphy joins the club and learns that it is as much about health as it is about finding sexual partners. When a third member of the club is killed, the police focus on Patricia Morris, who was seen leaving the club with him but another possible suspect is Belinda Fletcher who has a previous record for stalking men. New evidence however points them in yet another direction.
