Wealthy New York City playboy Arthur Bach (Dudley Moore) is perpetually drunk and completely rudderless. Dutifully supported by his sharp-tongued and quick-witted butler, Hobson (John Gielgud), Arthur reluctantly prepares to enter into an arranged marriage with heiress Susan Johnson (Jill Eikenberry). When he meets Linda Marolla (Liza Minnelli), a waitress from Queens, he falls head over heels in love, but if he backs out of his engagement with Susan, he may lose his fortune.

Upper-crust executive Louis Winthorpe III (Dan Aykroyd) and down-and-out hustler Billy Ray Valentine (Eddie Murphy) are the subjects of a bet by successful brokers Mortimer (Don Ameche) and Randolph Duke (Ralph Bellamy). 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.
