Lillian Harvey plays Miquette, whose beauty and vivacity increases the clientele of her mother's tobacco shop. A Barrymoresque actor (Lucien Baroux) believes that Miquette has star potential, but he hasn't sufficient capital to finance her theatrical debut. He manages to get the money by practicing a bit of genteel blackmail on an aging marquis (Andre Lefaur) who has romantic designs on the heroine.
