5 years after Freddy vs. Jason, Freddy Kreuger finds himself trapped within the conscious of Jason Voorhees. He then tricks Jason into finding the Necronomicon, aka the Book of the Dead, inside the old Voorhees house to free himself of Jason's mind and restore his nightmare abilities. The only thing standing in his way is Ash Williams, who has traveled to Crystal Lake to destroy the book once and for all. Ash meanwhile will have to deal with not just Freddy and Jason, but escaped mental patient Michael Myers as well, who has traveled to Crystal Lake to track down his nephew John Tate and his wife Molly. Armed with his chainsaw, boomstick, and a mysterious puzzle box supplied by a woman named Kirsty Cotton, Ash will ally himself with a group of teenagers and the survivors who clashed with the horror villains years ago to defeat the slasher villains once and for all.
