Der Moral der Ruth Halbfass is based on a true story, but modifies the facts slightly for cinematic purposes. The mores of the patriarchal German haute bourgeoisie regarding women are satirized here. Ruth (Senta Berger) has grown weary of being dependent on her wealthy husband, a playboy in his own right. She has a lavish affair with an impecunious married art teacher. The affair is hard on her pocketbook, and her husband is growing suspicious, so the adulterous couple discuss doing away with Ruth's industrialist husband. ~ Clarke Fountain, Rovi
