In Austria, the American traveling salesman Virgil Smith arrives in the palace of Emperor Franz-Joseph I with his mongrel dog Button expecting to sell one gramophone to him to promote his sales in the country. However, the guards believe he has a time-bomb and he does not succeed in his intent. When the dog Sheherazade of the widowed Countess Johanna Franziska von Stolzenberg-Stolzenberg bites Button, Virgil visits her and sooner he falls in love for Johanna and Button for Sheherazade that is promised to breed with the Emperor's dog. When Virgil asks permission to marry Johanna to the Emperor, the nobleman exposes to the salesman that their difference of social classes would doom their marriage and offers a business to Virgil.
