A Passion to Kill (1994)

About this title: Scott Bakula inagurates an illicit romance with the very married Chelsea Field. When Field's husband turns up murdered, Bakula can't help but feel that his bedmate is responsible. Should he act upon his suspicions, or just live for the moment? Here's an added wrinkle: Bakula is a psychiatrist. Never entirely predictable, this steamy melodrama contains what used to be called a "wow finish". Hal Erickson, All Movie Guide
