Unscrupulous football team owner George Kennedy will get $1 million tax-free if he lives up to the terms of his recently deceased father-in-law's will. He has to restore the old man's favorite train, the Chattanooga Choo Choo, and make a 24-hour run from Chattanooga to New York. Kennedy sees this as his chance to get free from his wife and get some publicity for his team. Kennedy's mistress (Barbara Eden), the team coach (Joe Namath), cheerleaders, players press, estranged wife, daughter, potential son-in-law and his father (who is also Kennedy's business rival), are all on board for the hilarious trip.
