The main character is Viktor Shtrum, a talented Soviet physicist who refuses to blindly follow his "comrades" by signing false documents and becoming a tool in the hands of an all-powerful state. During the war, Shtrum’s mother, Anna Petrovna, was sent to a concentration camp, but her letters continued to arrive for many years and help him remain more moral than those around him.
