When a woman hopes that a night of passion will grow into something deeper, she finds that her new beau may have some secrets in this erotic thriller. Ever since her divorce, Michelle Sanderson (Ally Sheedy) has tried to focus on her career in advertising, but she's become terribly lonely, and when she meets handsome stranger Jack Gillman (A. Martinez), without thinking, she joins him at his apartment for a long night of lovemaking. The next morning, she discovers that Jack is gone, along with his furniture; when she comes back later in the day, a man named Michael Joslyn (Frederic Forrest) is living at Jack's place and claims to know nothing about him. Jack eventually calls Michelle, and she sees him again; he tells her that he runs a construction business and that his wife passed away not long ago. However, Michelle later encounters Michael and his wife (Diane Salinger), and she discovers that they were the parents of Jack's late wife -- and that they're convinced that Jack is responsible for her death. One Night Stand marked the directorial debut of actress Talia Shire, best known for her roles in the Rocky films.
