When an auto accident robs Chris Smith (Robert Webber) of his memory, his only link to the past is a torn photo of a beautiful woman. Tracking down the photographer, he discovers the model was killed six months earlier, stabbed to death in her shower. But when he's repeatedly awakened by a woman's screams and later finds her dead body in his bathroom, the question frighteningly arises: is Chris a killer gone insane or a pawn in a well-planned murder? Stylishly directed by Academy Award-winning cinematographer Freddie Francis from an original screenplay by the legendary Jimmy Sangster, Hysteria is Hammer Studios meets Hitchcock on a suspenseful high wire!
