Monty Brewster inherits his deceased uncle's fortune, but Brewster must play a game to gain the entire inheritance.
Richard Pryor plays Monty Brewster who is an unknown minor league baseball player for the Hackensack Bulls. He and a friend Spike, who is played by John Candy, get into to a bar fight which lands them in jail. They are bailed out by a photagrapher, and he led Monty to a lawyers office. The lawyer informs Monty that his uncle, which he didn't know existed, has died. The uncle left him his entire estate which is worth approximately $300,000,000, but in order to get the inheritance he must play a little game. Monty can either take $1,000,000 no questions asked, or he could get the $300,000,000 by spending $30,000,000 in 30 days. It's not that easy because the entire $30,000,000 and all his assets must be completely gone in 30 days. The most difficult stipulation is that Brewster can not tell any one about this challenge.
Brewster starts immediately by throwing large sums of money away by giving his friends and strangers jobs with outrageously high salaries. Brewster then rents an entire floor of a fancy hotel and throws large expensive party's. From the start Brewster thinks it will be easy, but there are a few obstacles in his way.
Brewster's friends begin to think he is crazy, and try their hardest to keep him from throwing his money away. They even make him large sums of money, and this adds more to his fortunes that he needs to get rid of. Another obstacle are bankers who have the intentions to foil Brewster in his quest of spending. If they can keep brewster from spending all the money in 30 days the fortune is theirs to keep.
Brewster has one final idea to spend all his money, he runs for mayor. He would run an expensive campaign that he thought was lousy. His campaign actually was successful, but he couldn't win because the mayor had a salary. He dropped out at the last moment, and had successfully spent all the money.
On his way to claim his inheritance he found that the bankers tricked him. They had found a way that had him still in possession of a $1,000. Brewster at the last second found a way to spend the rest of the money. He was close to losing the game, but he successfully spent it all with only seconds left till the game was over. He then claimed his $300,000,000 happy that he can enjoy his inheritiance rather than be pressured to spend it all.
