The plot kicks off with Ash locked away in a mental institution following the events of Evil Dead II (ignoring Army of Darkness entirely). A doctor, attempting to use the Necronomicon Ex-Mortis for research, accidentally unleashes a horde of Deadites. Ash, freed from his cell, faces a new threat: a half-Deadite creature named Sam, whom Ash reluctantly adopts as a dim-witted, chainsaw-wielding sidekick. Together, they must stop a madman from merging the human world with the Evil dimension. The story is nonsense—gloriously, intentionally so—and serves mainly as a vehicle for Ash’s insults, Sam’s burbling, and creative demon-slaying.
The story opens with Ash committed to Sunny Meadows, an asylum run by the deranged Dr. Reinhard. Simultaneously, a journalist named Sally Knowby (descendant of the professor who found the Necronomicon) accidentally awakens the evil once more. This setup allows the game to explore a side of Ash rarely seen: the incompetent, institutionalized patient, which naturally transitions into the reluctant hero fans love. the evil dead regeneration
