How difficult it is to be a mentor if you yourself do not fully know what you want from life. Fil is a professional football player who, due to an injury, has to work in his profession - as a teacher. But even here, everything does not go as smoothly as the young man would like. Fil is fired from school for his overly radical teaching methods. In order to earn money for an operation and return to big football, the hero has to make ends meet with tutoring and odd jobs. But one ridiculous accident changes everything: Makar, the 13-year-old son of crime boss Lemur, falls into his hands. Now Fil will have to not only raise a little sociopath who dreams of a mafia career, but also help the district police officer's daughter Dasha enter MGIMO, despite her father's resistance. Fil is forced to learn to be an adult, raising a difficult teenager, and for the first time he truly risks for others, breaking his philosophy of an eternal slacker.
