The Strange Vice of Mrs Wardh(Lo strano vizio della Signora Wardh)

Newly married to an older man, Julie returns to Vienna, where a razor wielding slasher is killing women. Jean, her cruel and sadistic former lover, immediately contacts her, certain that only he can satisfy her strange vice. But she rejects him. She also meets George, the handsome cousin of her friend Carol; both are newly rich, thanks to an uncle's death. Julie's husband Neil is away frequently, so George pours on the charm. Meanwhile, it seems that the slasher is now focused on Julie. Bodies pile up, other murders are barely avoided, and George invites her to go away with him. Can it end happily?
