A determined and confident man all his life he dreamed of living in the Middle Ages. And then he died... Having resurrected after a car accident in the past, Dmitry realizes that he has become a young prince, who in the future will be called Donskoy. But now no one suspects this nickname, considering the young man a poor heir to his great ancestors.

Having gathered the lands of Rus' into a single fist with iron and blood, Dmitry will explain to neighbors like Mamai, Tokhtamysh and Olgerd that now our country must be reckoned with, respected and feared.
