Since childhood, the operative Gosha Kotov dreamed of becoming as cool as his legendary father, who died in the line of duty back in the 1990s. At first, Gosha does not really succeed in catching criminals, because he is a coward, but by the will of circumstances, an infected dog bites him, and the guy becomes a werewolf — incredibly strong and dexterous, with an acute sense of smell and hearing. But what remains unchanged in Gauche is his keen sense of justice. From that moment on, he begins to actively fight crime, as well as solve his personal problems.
