Larry (Anthony Perkins) is not someone it is wise to cross, as his wife Frances (Jill Ireland) discovers. In this English-language French melodrama/thriller, Larry uses his skills as a neurologist and brain surgeon in an attempt to manipulate a hapless amnesiac (Charles Bronson) into murdering his wife and her lover. The amnesiac was found on a beach along with the body of a dead woman, and he is already suspected of her murder--why not add another to the list? ~ Clarke Fountain, All Movie Guide
