Soon Fritz is declared missing and the old cobbler dies of grief. Along the way Franz, who dodged the military service, earns his money with large-scale racketeering. Frieda is miserable. But then Fritz returns from Soviet captivity, prompting Frieda to divorce Franz. Finally Frieda accepts an inheritance from the USA and marries Fritz. With the money they open up a shoe store.
