Strange things are happening on the territory of the Chernobyl Exclusion Zone. Mutants one by one and in groups are drawn to the depot, as if something attracts them there. The bandits are completely loose and behave as if they are the owners here. A camp of scientists on the shores of a round lake turned into a breeding ground for zombies. Stalker Sergei Rodnopolsky, nicknamed the Sorcerer, guesses what was the reason. Its dark essence has found a new body, and now the very existence of the Zone is under threat. Stalker enters the battle with the eternal enemy. But before delivering a fatal blow, he needs to answer the main question: what is he willing to sacrifice to win this war?
