Upper-crust executive Louis Winthorpe III and down-and-out hustler Billy Ray Valentine are the subjects of a bet by successful brokers Mortimer and Randolph Duke. An employee of the Dukes, Winthorpe is framed by the brothers for a crime he didn't commit, with the siblings then installing the street-smart Valentine in his position. When Winthorpe and Valentine uncover the scheme, they set out to turn the tables on the Dukes.
