After years of being shuffled around various mental institutions, Tommy Jarvis has now been placed in the Pinehurst halfway house, one that is unique because it runs off an honor system. It is not made clear what happened to Tommy's sister, Trish, following the events of the previous film, but he apparently has no contact with her. Shortly after arriving, one of the patients murders another and is arrested. Soon afterwards, a series of murders begin to occur around the area. With Jason Voorhees dead, the identity of the assailant remains unknown.
