Endre Julián, the young toy maker, lives a life of leisure. A man with a devious nature, he has his eye on the beautiful daughter Vera, the police inspector János Kántor. He takes her to his weekend home, but she realises that he is looking for an easy fling with her. An unfortunate accident causes Vera to disappear in deep water, and Endre notifies the police, telling Inspector Kántor the bad news. Eventually she is lucky enough to be found, but she doesn't want to hear anything about the toy maker. Endre's fatherly friend, Uncle Reményi, is very taken with the serious girl and decides to bring the young people together.
