After the terrible accident at the Chernobyl nuclear power plant, the radioactive contamination zone was surrounded by a cordon. The government banned passage behind the barbed wire on pain of death, because terrible and inexplicable events began to occur there, which it was better for the population of the planet not to know about. The facts were made public in the press: everyone who worked at the Fourth Power Unit died, the background radiation in the Zone is still extremely high, its territory is teeming with mutants and anomalies, so people have nothing to do on the dead earth. But one day a man comes out of the Zone to the cordon, who says that there, on the contaminated land, there are survivors who can still be saved. The government is urgently forming a team of rescue scientists. And the only one who can lead them to the center of the Zone is the stalker, who miraculously managed to stay alive after that terrible accident.
