1947 ... The Savchenko family returns to Moscow from evacuation - husband and wife with Kostya's little son. They settle with Grandma Kostya in a huge communal apartment. Street meets the boy with a flock of local boys. Then there were: the division of the territory with the "Sretensky"; trophy movie “Girl of my dreams”; a school with separate education, camp discipline and essays about the border guard Karatsyup. And the monetary reform of 1947, when all of their savings depreciated in an instant, and the boys let out boats from banknotes in puddles.
