Late Middle Ages. Eve of the Battle of Grunwald. But everything goes wrong. Everything is different.

The Swiss battle bristling with pikes and the Austrian knights opposing it burn in atomic flame. The Emperor of the Holy Roman Empire, who entered into secret negotiations with the German crusaders, was shot with a machine gun.

Here, black Teutonic crosses coexist with a fascist swastika. Here the unfortunate mutants are declared fiends of hell. Here they rush at a knight clad in armor with a sapper's shovel and at a motorcycle with a spear. Here they fire from a giant bombard at an armored personnel carrier and use rapid-fire crossbows against the “Schmeissers”. Here, former riot policeman Vasily Burtsev must save this whole wrong and so fragile world.
