The Russian army, contrary to history, won the battle on the Kalka River. It seems that the threat has passed. But the Mongols do not forgive the insults caused to them. Under the influence of those who came to ancient Rus', history took an intricate zigzag. Genghis Khan unexpectedly dies at the hands of unknown assassins, not having time to transfer the rule of his empire. After numerous bloody internecine clashes, his grandson Batu comes to power. Sudebey persuades him to send his army to the west again to punish the treacherous Uruses. And here again countless hordes are marching on Russian land. And only one person can prevent a new tragedy - former KGB major Dmitry Gordeev.
