The heroes of the film are sixth graders. There is an inventor among them, a badass, there is unquestioned authority and the first beauty. And there is also the headman Lyalya Ivanova, who wanted to “raise” her diving champion in the classroom in a short time to take first place in the school competition. Vitya Onishchenko became a candidate for the champions. To achieve the goal, all means are good for Lyalya, even dishonest ones, and therefore she pulled the whole class into this “event”: someone was preparing lessons for Vitya, someone was “working out” a possible rival. But all the tricks finally failed: the guys realized the obscenity of such methods of achieving success.
