Conversion of Ferdys Pistora

Cashier Ferdyš Pištora goes to rob the villa of banker Rosenštok. At that moment, a fire breaks out and Ferdyš saves the banker's two young children. He is hailed as a hero by everyone and Rosenštok makes him a messenger in the bank. This changes Ferdyš's entire life. He becomes a moralist and bullies the whole neighborhood with his sermons. He falls in love with Terezka, a member of the Salvation Army. Ferdyš's former lover Irma is jealous of Terezka. The two women argue and Terezka, in anger, claims that she killed her child and buried it in the cellar. Ferdyš believes this fabrication. In order to save her, he wants to give her the money that he was supposed to hand over to the bank. Out of jealousy, Irma tells the police that Ferdyš wanted to rob the banker's villa, and Ferdyš is arrested. However, Rosenštok intercedes for him and Ferdyš is acquitted. Terezka confesses that she made up the child's murder and celebrates her wedding with Ferdyš.
