trade a Dimond hair pin for a car

Brewster, an aging minor-league baseball player, stands to inherit 300 million dollars if he can successfully spend 30 million dollars in 30 days without anything to show for it, and without telling anyone what he's up to... A task that's a lot harder than it sounds!

Monty Brewster is a pennyless, former U.S. Army soldier back from World War II Europe who learns that he has inherited $8 million from a distant relative. But there's a catch: he must spend $1 million of that money in less than two months before his 30th birthday in order to inherit the rest.
