The world after the Third World War. Nuclear winter, people live in bunkers and shelters, fighting for the remains of clean food and fuel. Here slavery is the rule, and the main law is the right of the strong. In such a world, the surviving officers and soldiers of the Russian army, remaining human, managed to find a way back to the past, to 1942. There is also a war going on there, and our contemporaries, who received a breath of fresh air from the past, had to take up arms again and fight shoulder to shoulder with their ancestors for the freedom of their Motherland. But by developing time travel technology, people gain access to 1914 and again see the war and the death of the Russian people. What should they do and whose side should they take? After all, they will no longer be able to stay away.
