Blade of the Ripper

Julie Wardh (Edwige Fenech) is a lovely but jaded woman who is no longer satisfied in her relationship with husband Neil (Alberto de Mendoza), a wealthy but emotionally cold man of privilege. However, as she ponders the fate of her marriage, her thoughts often turn to her former lover Jean (Ivan Rassimov), a cruel libertine with a taste for inflicting pain. Julie meets handsome George (George Hilton) at a wild party and discovers he's attracted to her just as she's drawn to him. Julie and George are soon involved in a torrid affair, but it's Julie's poor fortune that Jean attended the party where they first met and knows about her new infidelity. Even worse, Jean is willing to blackmail Julie to get what he wants, forcing her into a desperate situation. (official distributor synopsis)
