Unique time travel setup connects two worlds. In one of them, the world of the future, a global nuclear war has passed, and the remnants of civilization are trying to survive in bunkers and shelters, desperately fighting for the remnants of food and fuel. Both the world of 1941, where the Great Patriotic War is going on, and the troops of fascist Germany are standing at the gates of Moscow. What will people who have lost their peace, hope and gained access to the world of the past do? Someone will try to be omnipotent, using the achievements of modern technology, and someone will, along with their ancestors, fight the enemy who attacked his homeland.
