Prince Igor.

Prince Igor enters the princely rights and organizes a new campaign to Constantinople, which ends in a military disaster. As a result of internal political turmoil Prince Igor dies, and the historical arena goes to his widow, Princess Olga. She cruelly takes revenge on the perpetrators of the death of her husband – rebellious citizens. After this Olga conducts a series of public reforms and again goes on Constantinople, but on this time not with war, and with the world. There she unexpectedly for her people receives baptism from the hands of the Patriarch of Constantinople himself. Trying to spread Christianity to the whole Russian land, Princess Olga meets a sharp opposition from her grown son, Prince Svyatoslav Igorevich. A great warrior and a convinced pagan, Prince Svyatoslav sees the future of his land not in the power of the spirit, but in the power of the sword.
