Copacabana (1947)

Talent agent Lionel Devereaux sells his girlfriend/client Carmen Novarro to New York City's famous Copacabana nightclub as a Latin-American singer/dancer and, pressed for another act, he sells her again, this time with a blonde wig and Moroccan veil, as a French singer...for the same presentation. The wear and tear on Carmen, changing back-and-forth between numbers, leaves to a heated exchange of words between the performer and her fiancé agent. This leads to the disappearance of Carmen's alter ego, which arouses suspicions by the management...and the police.
