The fighters of the Mammoth special forces unit, where Yurka Taran served, have no easy tasks: you can easily run into a bullet or a knife, but the worst thing is to be captured, no matter by bandits or cops. No one will intercede - you can’t expose “Mammoth”. So Taran acts, carrying out the next task, at his own peril and risk: he shoots when it is impossible not to shoot, runs away when there is no other way out, prepares for death when it is nearby. He's lucky: he escaped a bullet, escaped gangster torture, survived the fire of an explosion... Couldn't he really be lucky here - in the underground labyrinth of a secret facility, where the fate of a fighter from the 'Mammoth' group has brought him?
