Joe (Curtis) and Jerry (Lemmon) have to flee town when they accidentally witness a mob mass killing. Best way to skip town? Dress up like women, of course, and join a women's band on its way to Florida.

Hilarity ensues as both men take turns falling for their band mate Sugar Kane (Marilyn Monroe), who confides to Joe's alter ego Josephine that she is hoping to meet a dashing millionaire in Florida. Even more hilarity as a millionaire man falls for Jerry's alter ego Daphne.
And the wonderful ending. If for some reason you have never seen the ending or had it quoted to you and you just love surprises, don't watch.
