Being a chorus girl is a family tradition for single mother May Martin (Adele Jergens) and her daughter, Peggy (Marilyn Monroe). But when the lead in the burlesque show they're in walks out, Peggy finds herself catapulted to overnight fame as the star attraction. May tries to advise her naïve daughter about those who would try to take advantage of her, especially her old socialite boyfriend, Randy Carroll (Rand Brooks). Peggy falls for him anyway, and it's unclear if his intentions are serious.
