He just wanted to travel around the roads and cities of Russia. But due to a fatal mistake, I ended up in a place from which I couldn’t get out either by car, or by plane, or even by spaceship. Where man is not the king of nature, but only one of the links in the food chain. Where today you are a hunter, and tomorrow you are the prey of a stronger predator... a two-legged predator, including. And the one who has a heavier club, a sharper spear and a stronger stone ax is right. The modern guy Senya finds himself in such a wild world. This is the world he will have to live in... or at least try to survive the next year.
