An out-of-work singer, Victoria Grant (Julie Andrews), meets a just-fired, flamboyant gay man in a diner in 1920's Paris. He convinces her to pretend to be a man who is a female impersonator in order to get a job. The act is a hit in a local nightclub, but things get complicated when a gangster and nightclub owner from Chicago, King Marchan (Michael Nouri) falls in-love with "her."
