While hunting, Prince Radúz of Maguria wanders into the rival kingdom of the Tatra King, Stojmír. He discovers that their nations' long-standing feud stems from the bitter jealousy of Queen Runa, who was once rejected by Radúz’s father. Radúz is soon captured by Runa’s forces after crossing the border. His fate becomes entwined with the royal family when it is revealed that the white deer he killed belonged to Mahulena, the King’s youngest and most delicate daughter.
