Irina, a small-town nurse, has a heart defect. According to the doctors' prognosis, her heart has not much time left to beat, and there is no one to take care of her six-year-old daughter Anna. Irina feverishly tries to find a way out and she gets the idea that Anya could be brought up by her grandfather - the father of the young man who left Irina pregnant. All she knows about her daughter's grandfather, Igor Vasilyevich Kutepov, is that he is a rather successful businessman and 63 years old.

Mikhail Petrovich Zorin is the last surviving signalman of the first composition of the legendary 330th Infantry Regiment (86th Infantry Division), who heroically fought on the Nevsky Piglet during the defense of Leningrad during the Great Patriotic War. In April 1942, in the course of a powerful onslaught of the German group, almost all the soldiers who were at that time in the regiment's location were killed, and the wounded were taken prisoner. Mikhail Zorin survived thanks to a unique combination of circumstances.
