Feri Noszty forges bills of exchange, which is an unforgivable sin in his circle. The family, to pay the debt and save the boy's honour, cash in their only fortune by marrying Vilma, Feri's sister, to a wealthy man. But this will not save Feri, who must resign his commission as an officer. He gets a job as a magistrate, but the income does not satisfy the young man's needs. All that is left is a good marriage and a huge dowry.
