Set in December 2008, 5 years after the events of the film "Freddy vs. Jason" and 16 years after the end of "Army of Darkness", the story begins with Will Rollins and Lori Campbell (the former protagonists from "Freddy vs. Jason") returning to Crystal Lake to put closure to their experience, but Jason kills them a short while after and takes their decomposed corpses to his shack in the woods nearby. There, Jason enters a trance, and Freddy and Jason's "mother" appear to him. Freddy Krueger is now trapped, powerless inside the mind of Jason Voorhees, where he learns of the "Necronomicon" hidden in the old Voorhees home, with the power to resurrect him. He and Jason's mother (false Pamela Voorhees) convince Jason that if he gets the Necronomicon, Jason will become "a real boy". Meanwhile, Ash Williams is called to the new Crystal Lake S-Mart to give his retail expertise to its team of teenage slacker employees. While there, he interprets a nearby Jason murder as work of the Deadites. Later, he follows a group of teens to the Voorhees house where he finds the "Necronomicon" before Jason appears, killing the teens.
