Paranoia

A race-car driver who's down on her luck is invited by her ex-husband's wife to stay at their plush villa. The two women form a bond, and it's not long before their mutual dislike for the husband culminates into a plan to kill him. As it turns out, though, they're not alone in plotting murder.
