A fourth-grader is looking for her father with the help of a friend.

Taking advantage of his intellectual superiority, the teenager Valya Uspensky subtly and mercilessly takes revenge on others for small and big offenses. The young mathematics teacher Igor Aleksandrovich also falls into the field of his interests, whose intelligence and tact will properly influence the guy. But the young intellectual will suffer a crushing defeat in the seemingly ordinary everyday situation, which will be set up for him by his sweet, pretty classmate Ira - if only in order to once and for all teach the narcissistic jester a lesson.

A teenage girl nicknamed Avariya - "Crash" - is a rebel child that just can't get along with her family members that try to persuade her to behave normally - that is as other people do. But when Avariya gets gang-raped, his father (who is a cop) breaks all the rules and goes out for revenge.
