Jackie Moon is the owner, promoter, coach, and star player of the Flint Michigan Tropics of the American Basketball Association (ABA). In 1976 before the ABA collapses, the National Basketball Association (NBA) plans to merge with the best teams of the ABA at the end of the season. Only the top four teams will make the move and the worst teams will fold. The Tropics are the worst team in the league and if they want to make it to the NBA, Jackie Moon must rally his team and start winning. Unfortunately, both Moon and the Tropics are a lot worse than they realise..
