Ben Masters, Brooke Adams, Daniel Stern, Danny Aiello and Tony Roberts round out the cast of this charming romantic comedy about the ups and downs of a young New York couple. Originally a popular off-Broadway play, Key Exchange is the story of Lisa and Phillip, who have been maintaining an open relationship. But now she decides it's time to take a step towards commitment, which entails an end to his fooling around and giving each other the keys to their separate apartments. However, this gives Phillip some problems -he still wants to fool around, and he's already seen the marriage of his best friend (Stern) disintegrate in short order. It's a bittersweet tale of romance, love, commitment and freedom, and the myths and realities that go with each.
