At the end of 13th and the beginning of the 14th century twenty-four-years old, Prince Svetoslav Terter takes the helm of the state. The young Prince engages in a intricate political game, into getting his way by means of court intrigues, and is forced by circumstances. Svetoslav Terter is remarkably shrewd and consistent. He is perhaps the only head of state at this time to take the liberty of impeaching the primate of the country's church. He tries to rally the neighboring Slav people to a joint resistance to the Turkish conquest. Terter lives through a great personal tragedy. He becomes estranged from his dearest person, Mariya, who is too weak to join him on the difficult road of his choice.
