Lisa (Brooke Adams) is dating Philip (Ben Masters), but the two don't have an exclusive relationship. While Philip is happy with the arrangement, Lisa wants something more, and pressures Philip to settle down with her. She gets Philip to reluctantly exchange apartment keys, but he still can't decide if he is ready for a serious relationship. Meanwhile, his friend Michael (Daniel Stern) has the opposite problem. He eagerly married his wife, only to find out that she was cheating on him.
