To prevent loosing her property to creditors baroness Margit von Bardy, conscious of her gifted voice, opens up an Autoczardas road inn with music and singing to attract travelers. One of them is Hans Berend, whom his aunt has made believe has lost his fortune and needs a serious work now. He takes Margit for a plain innkeeper, both soon feeling attracted to each other, and has the brilliant idea of opening a gas station to complement the restaurant. Now he only needs the baroness'approval. Not wanting this nice but poor young man to know the truth about her, she arranges a meeting with her maid as baroness. Problems will soon appear.
