Eddie Murphy established himself as a comedy superstar in his role as streetwise hustler Billy Ray Valentine. Fellow Saturday Night Live alumnus Dan Aykroyd co-stars as Louis Winthorpe III, a wealthy investment executive at Duke Brothers, a Wall Street firm.

The fun begins when the rich and greedy Duke Brothers (Don Ameche and Ralph Bellamy) wager a bet over whether born loser Valentine could become as successful as the priggish Winthorpe if circumstances are reversed.

The Dukes have the money to make this happen, but when Valentine and Winthorpe catch on they arrange for a rich and riotous payback!
