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.
