It centers on the life of the middle-class family of Lazarov, which is torn by the sharp political contradictions taking place against the background of the popular struggle against fascism. The father Vitan goes through terrible mental traumas, which are the price, he has to pay for his illusions that in such clashes one can remain neutral and free from politics. The partisans execute the son Boris - a fascist officer, a sadist and a murderer. The daughter Lily is forced to search for her place in the conflict between the representatives of two hostile worlds - that of fascist brother and her husband - a communist and a revolutionary.
