Finally, Mark and his partners met the enemy face to face, but the seemingly final goal was only a fragment of the struggle of global forces that are far beyond the Zone. The masters of the Great Game, at any cost, need to find something important in the radioactive lands of the forbidden territory, something that can change the course of all history. It is becoming increasingly clear to many who were involved in the frantic whirlpool of events that the stakes in this confrontation are much higher than previously thought. In an attempt to maintain the initiative, the enemy decides to act proactively, not disdaining any methods in achieving its goals, even if this means destroying everything in its path. However, the threat does not only come from outside. The betrayal of Colonel Seregin is also part of a multi-pronged and coordinated attack against the national interests of Russia.

After all, a Russian intelligence officer has no right to surrender, because for him, fulfilling his Duty is above all.
