Washed-up baseball player Montgomery Brewster (Richard Pryor) learns he's inherited a $300 million fortune from his deceased, rich uncle. To get the cash, however, Brewster must spend $30 million within 30 days -- and have absolutely nothing to show for it. Baseball buddy Spike Nolan (John Candy) helps Brewster with his spending spree while snooty attorney Warren Cox (Stephen Collins) watches his every move.
