As a result, the undead serial killer Jason Voorhees (Kane Hodder) is resurrected once again. He immediately finds the boat's occupants, a high school couple named Jim Miller (Todd Shaffer) and Suzie Donaldson (Tiffany Paulsen), having sex. Obtaining a new hockey mask from the boat (which Jim had previously used to scare Suzie), he kills Jim with the barrel of a harpoon gun.

The trip is chaperoned by Colleen Van Deusen (Barbara Bingham) and biology teacher Charles McCulloch (Peter Mark Richman), who has also brought along his niece, Rennie (Jensen Daggett).

Jason then starts murdering the people on board, starting with a wannabe rock star named J.J. (Saffron Henderson), whom he kills by bashing her head with her own electric guitar.

Her dead body is later discovered lying on the floor.Jason then kills the captain of the Lazarus, Admiral Robertson (Warren Munson) and the chief engineer Jim Carlson (Fred Henderson), leaving the two chaperones, Rennie, and the remaining students...
