Syn chempiona (1979)

Shurik Kleymenov, the son of a famous ski coach, goes with his father to competitions. At first arrogant, Shurik, watching the difficulty of the path to sports victories, eventually begins to understand that sport can become a worthy goal for him in life. Meanwhile, coach Kleymenov finds himself in a difficult situation: the downhill track he chose did not live up to his assumptions and one of the participants is injured.
