A teenager from a privileged family, Grisha, moves from Volgograd to Kazan and finds himself in the epicenter of a street gang war. He is a stranger in this world, but in order to survive, he is forced to learn its cruel rules. An unexpected mentor for him is the ideologist of the Tyap-Lyap gang, Zakharevich - a smart, educated and ambitious manipulator who created a system for drawing teenagers into organized crime. The only one who realizes the impending threat is the head of the criminal investigation department, Nikonov. It will take him time to understand that this is not just a criminal outbreak, behind which there are extraordinary figures, but the beginning of large-scale processes that can destroy the country.
