The film tells about the childhood of Yuri Gagarin, about that time of life, which, in his own words, played an important role in shaping his character: war, the occupation of their villages by the Germans, famine, the theft of the elder brother and sister to Germany, the expulsion of the Nazis from Smolensk, moving family in the city of Gzhatsk.
