Salesman Virgil Smith (Bing Crosby) is making his next big move in Austria, pushing the gramophone. He believes that if he can persuade Emperor Franz Joseph (Richard Haydn) to purchase the record player, he’ll strike it rich as the nation follows suit. However, in the meantime, Smith falls for a countess (Joan Fontaine), a woman in a class above his own. Now in addition to convincing the emperor to buy his wares, Smith must also find a way to receive the emperor’s blessing to marry his love.
