The villa in the story of László Vadnai is for sale. The owner goes away and leaves the house to his butler, who also entrusts its safekeeping to an old friend. The friend immediately moves in with his niece, and two swindlers appear. But who is the seller and who is the buyer, and why the villa has to be sold at all, is a question that is only answered satisfactorily at the end of the film, after a lot of wall-crawling humour.
