Popular football player Anton Kovalev, after spending two years in prison for a drunken brawl in a cafe, is released. The offense blocked the successful career of Kovalev, who was previously the captain of the Russian national team. The reputation of a "downed pilot" does not allow him to continue his favorite business and get a prestigious job. The head of the center for difficult teenagers, Herman, who once raised Anton, offers him a place in the center to prepare difficult children for the local Olympics. Out of desperation, Kovalev agrees to the offer, but he does not even imagine how difficult it will be to find a common language with the guys, and what an important place they can take in his life.

Zakhar is the head of a big family who spent all his life living in a village in a private house. He is also the only one who refused to sell the land for the construction of a new residential complex. After all, not only his right to private property but also his happy memories are under threat: the old forest he knew since he was little was cut down, and the pond where he used to fish with his father was drained. Moreover, his grandson fell in love with the developer's daughter! While life seems to fall completely apart, Zakhar, together with his family, decides to stand his ground to the very end against urban developers, dissatisfied tenants of the newly built high-rise, and total injustice.

Zhora, along with his parents, moves to another city, where he cannot establish relations with classmates in any way, and teachers openly find fault with him. Tired of enduring total injustice, Zhora decides to fight it, and in a non-standard way: a student puts a helmet with a camera mounted on his head and begins broadcasting everything he sees at home and at school to the Internet.
