Solicitor Lukács is well known for his expertise in divorce. He lets a room and while he is away, Csahos, his articled clerk, in charge of business affairs in the absence of the solicitor, leaves almost all of the flat to Székely Klári, a pretty university student. Lukács, while driving his car to Siófok, accidentally bumps into his wife and their friend, Bognár Miklós. Misunderstanding the situation, he asks for a divorce.

Among the Gruber family, the rumor spreads like wildfire that their wealthy American relative, Menyhért Gruber, is visiting Hungary with his daughter, Mary. Various plans are devised to exploit the rich relative. The boldest of them all is the plan of Bálint Koltay, who directly pursues Mary's hand. However, the young ones fall in love with each other so deeply that Bálint stands by Mary even when the "wealthy" Gruber informs him that he's bankrupt. At this point, the only thing left to arrange is for Bálint, who poses as a landowner, to actually present a noble castle to his future father-in-law.
