A story about a family after the Second World War. The petty bourgeois cashier Karl Weber of Berlin observes from a distance how his son Ernst participates in the building of a new socialist society. Karl does not understand Ernst's visions, instead he confides in his other son Harry. However, Harry becomes involved in illicit business and Karl quickly realizes that it would be best to join his son Ernst in the citizen-owned factory.
Hans Albers plays returning war veteran Hans Richter who has trouble finding work. With nowhere else to turn, Richter gets involved with black market activities. This so disgusts Richter's son, blind ex-soldier Edwin (Paul Edwin Roth), that the boy literally disowns his father. Hans eventually mends his ways, but not before several other devastating setbacks.
