During testing a new superweapon at a closed test site, something went wrong. Instead of making modern soldiers invulnerable, the machine created by leading Russian scientists opened the door to the past, and the warriors of the great conqueror Subudei emerged from the witchcraft fog, reliably protected from bullets and shells. The army, which has relied on high-precision weapons, has nothing to oppose them. It's one thing to sit in a warm bunker and press a button to send homing missiles at a target. And it’s quite another thing to come face to face with the enemy, chest to chest, in the middle of the snowy steppe, feel his breath on your face and, in drunken excitement, draw blood with a curved blade... Those who are trying to block the way for the invincible tumens are left with a limited choice: learn to fight in hand-to-hand combat, stand to death, when the equestrian lava overflows the flimsy front gardens, or share the pitiful fate of a slave... But real men have not disappeared in our time: in the path of the invading army, captain Dmitry Kosov, who has gone through fire and water, will stand, one of those few who have not forgotten how to look death in the face and I’m not used to surrendering to the mercy of the winner.
