For their vacation, Ash, his wife Linda, their friend Scotty, and his wife Shelly travel to an apparently abandoned woodland cabin, where they find a recorder, audio reels, and an old book. Scotty plays one of the reels, which were made by the cabins owners, Professor Raymond Knowby, and his wife, Henrietta. The reel reveals that the professor and his wife were working on translating the book, a seemingly demonic sex guide known as the Necronomicum ExMortis. While reciting a mantra that he found in the Necronomicum, Knowby seemingly went insane, laughing maniacally as he repeated the words over and over again, awakening an evil force. The group ignores the reel, and while Shelly goes to lie down, Ash, Linda, and Scotty have a threesome in a bedroom. Shelly walks in on the trio and, distraught over Scottys infidelity, runs out into the forest, where she is violated by possessed trees that turn her into a Deadite. Shelly returns to the cabin, knocks Ash out, and stabs Linda with a piece of bark that she pulls out of her vagina, infecting the other woman with the evil. Shelly proceeds to seduce Scotty, have sex with him, and rip his throat and testicles out. When Shelly tries to attack Linda, Ash fends her off with a fireplace poker, and locks her in the cellar, but she escapes, and begins having sex with the now demonic Linda. Aroused by the sight of the two Deadites going at it, Ash tries fingering Shelly, which results in his hand becoming possessed. Ash is forced to cut his hand off with a chainsaw, which he then uses to kill Shelly by forcing her to ride the tools blade. Linda, who has returned to normal, confronts Ash with a locket identical to the one that he had earlier given her. Inside the locket is a picture of Ash having sex with another woman, which angers Linda to the point of causing her to turn back into a Deadite. Ash and Linda wind up having sex; afterward, Ash beheads Linda with the chainsaw, and takes her body out into the woods to dispose of it. Lindas stillliving severed head taunts Ash, annoying him into masturbating onto it out of spite. Ash returns to the cabin, and goes into hysterics when the furniture and fixtures including a mounted deer head go haywire. Outside, Linda who has reattached her head rises from the grave, along with Deadite versions of two of Ashs exgirlfriends. Ash tries to kill the Deadites with the chainsaw which he has replaced his missing hand with but it will not start, leaving him unable to fight off the demonesses as they force him into an orgy. The reverse gangbang ends with Ash using the now functional chainsaw to dismember the undead women as he quips, Groovy!
