An unexpected death turns lovers into rivals in this thriller. Richard Mannhart (Perry King) is an unhappily married author who is having an affair with Katie Griffin (Roxana Zal), a film editor. Richard is mostly interested in sex, but Katie has become deeply infatuated with him. However, when Richard's wife, Laura (Susan Blakely), dies in a suspicious-looking auto accident, Katie tells the authorities that she has reason to believe Richard sabotaged his spouse's car. Richard angrily denies Katie's allegations and then goes on to deny any involvement with her. Trying to weigh one story against the other, the police tell both Richard and Katie that it's up to them to prove the validity of their stories. So what evidence can they produce to clear themselves and incriminate their lover? Also released as A Clean Kill, Her Married Lover also features Michelle Green, Daniel Benzali, and Terrence "T.C."
