Sibling Rivalry

Marjorie (Kirstie Alley) is the woefully neglected wife of a successful doctor (Scott Bakula). Egged on by her indignant sister (Jami Gertz), Marjorie decides to get back at her husband by having an affair. While out shopping, she's seduced by a stranger (Sam Elliott) and decides to go for it -- but the tryst turns twisted when the stranger dies of a heart attack and Marjorie discovers he's actually the brother of her self-absorbed spouse!
