He is not a superman or a special forces fighter. He does not know how to shoot from the hip and break bricks with one blow of the palm. He is not young and does not play sports. He is not a superhero. But he is used to saving people's lives, winning them back from death. He is a doctor. And when Death came to the planet, he entered into battle with her shoulder to shoulder with the few survivors. Deadly virus "six," dying cities and countries, crowds of the living dead, whose bite is fatal for any living. And the living - who are sometimes even more dangerous than the dead. Can a simple doctor survive the apocalypse? Survive and save relatives? Will humans be able to stop Death?
