It's All About the Brother (1977)
Family
Director: Valentin Gorlov
Two completely different sons grow up in the same family. The youngest, Frol Kalitkin, is an exemplary seventh-grader, winner of Olympiads, the first student. And the eldest, Andryusha, is a loafer, a loafer and a dude. The “correct” Frol takes up the upbringing of his brother.
