Two years after Tina Shepard's deceased dad chained Jason to the bottom of Camp Crystal Lake, two graduating high school students are aboard on a houseboat. One of their names is Jim, who tells his girlfriend Suzy the legend of Jason Voorhees; the supernatural while aboard undead psychopathic killer before playing a prank on her with a hockey mask and a fake knife. The boat sails over some underwater cables, which electrocute Jason's corpse and cause his resurrection. He sneaks on board and stabs Jim with a harpoon barb before impaling Suzy, who tries to hide from him.
