Jimmy Dworski (James Belushi) wins a couple of tickets to a baseball game by calling in to a radio show. The only problem is that Jimmy is in prison and serving his last two days of his sentence. Jimmy, with the help of other in-mates, escapes to watch the game. Spencer Barnes (Charles Grodin) in the meantime is on a business weekend and loses a briefcase that contains cash, credit cards and keys to a mansion. Jimmy finds the case and sees the opportunity of a lifetime and starts to pose as Barnes. While the real Barnes is searching feverishly for his briefcase Jimmy is getting into trouble every where he turns. There is no avoiding the fact that the two will eventually meet.
