Vocalist Toni LeBrun leaves her aunt's bakery for Budapest to become an "opera singer," unaware that she has contracted to perform as a chorus dancer at the Palais de Paris. Toni soon loses her job when she repulses Henry von Glessing, a rich patron of the dancehall proprietress. She and Rosa, the wardrobe lady (a poverty-stricken baroness), take up residence in a posh hotel in Monte Carlo. There, Richard Spanyi, a guest at the hotel, smitten with Toni's beauty and her skill at the piano, at first shocks her with his impetuous manner; later, they become sweethearts. Toni, heir to a title because Rose adopts her, gets engaged to Spanyi shortly before her money runs out. She refuses when Spanyi's uncle, Henry von Glessing, tries to buy her off, and the wedding proceeds.
