Champagner (1929)

Jenny, a cheerful kitchen maid at the Paris-style Palais de Luxe, is hopelessly in love with charming head waiter Jean—only to be stood up when he forgets their planned tryst in favor of the hotel’s glamorous dancer, Lola. Humiliated and on the verge of arrest for “stealing” champagne, Jenny hides backstage where she’s mistaken for a performer, wows the crowd with an impromptu dance, and finally wins Jean’s heart.
