Police Captain Nikolai Markin is going to the location of a maximum security colony somewhere in the taiga. He has a secret mission. But he does not have time to get to the colony: three kilometers from the entrance to the zone, Nikolai becomes a witness to the escape of a prisoner, Dmitry Voronkov. Without a second hesitating, the officer rushes into the woods in pursuit of the criminal. Unlike the prisoner, who was clearly preparing to escape, Nicholas has no card, no food, no weapons. Nevertheless, he stubbornly follows the fugitive.
