Five young dunces could not come up with better entertainment than to go on an illegal excursion to the Chernobyl nuclear power plant area. A long hike - how boring! And as luck would have it, there’s not a single decent anomaly, not even anything to brag about... But the stalker-guide turns out to be not who he claims to be, and the forest animals are not at all so harmless, and the machine gun aimed at the forehead actually shoots, and there’s background radiation - is not at all a fiction. A group of student excursionists turns out to be disunited, and then the Zone takes them seriously. Wrong decisions, irreparable mistakes, irreversible changes - and now you yourself can’t say for sure whether you are human. And if still yes, what price will the Zone ask for when you get ready to leave it? Will she hear the silent plea of her new toy?
