A scientific experiment launched by scientists ended in a global catastrophe. Part of our world was moved into a parallel space, where Earth turned into a post-apocalyptic hell: destroyed cities, radioactive sand, mutants, religious fanatics. By chance, the former lieutenant of the marines, Vsevolod Burokov, and his companions ended up in this hell. Fate left them only two options: live or die. They chose life. And that means everyone who dares to stand in their way will have to die too.
