In a fight for the monarchy, Sverker III killed Eric's brothers and has a result, lost his crown in a revolt of nobles. Though a mere youth, Eric X becomes the new king, with Folke Jarl as the chief magistrate of the realm. During the fighting, Folke's son, Sune, was captured by Sverker but regained his liberty. Sune captured Helen, and, though she pleaded to return to her father, he kept her as the king's prisoner. To maintain peace, Eric proposes to marry Helen, which astonishes Sune, who intended to marry her himself, with her's father approval, since the latter still cherishes hopes of regaining his crown with Sune's help. Helen loves Sune, but now feels abandoned by the luckless youth. Feeling that it is up to her father to dispose of her, she asks Sune again to send her to him. To foster more friendly ties with Sverker, Sune attempts to convince the king to release her, but he refuses. Folke scolds his son for this attempt. To many of the nobles, June's sentiments seem suspicious, appearing more loyal towards Sverker than the king. To free his daughter, Sverker arrives at court disguised as his own messenger. He reiterates his intention of making Helen Sune's wife should the latter revolt against the king. Sverker's disguise is rapidly discovered. In answer to Eric's plan, he says he promised Helen to another. For his ambiguous role in this affair, Eric has only hard words for Sune, who angrily draws his sword. Folke does not hesitate to order his son's removal from the court. Late at night, Sverker returns with conspirators to meet Sune once more. "You have me in your power," says Sune, still smarting from the king's suspicions, "you have armed me. Let not my anger time to cool, but guide my steps." With Sune's help, Helen escapes. On discovering this, Folke is incensed against his son, who yields his sword to him. Folke presses Sune's condemnation, but, in view of his past services as well as those of his father, the king pardons him. The king abandons the idea of marrying Helen, now convinced this will not bring peace to their two houses. When the king asks Sune to become his friend, he exclaims: "Your friend and Sverke's son-in-law!" convinced the two cannot be reconciled. The king gives Sune his own sword to fight his enemy. Feeling Sune is in mortal danger to his own party, Helen returns to the king to plead on his behalf while the nobles raise arms in open revolt. Sune encounters Sverker and stabs him. Though the cause of his death, a dying Sverker requests a remorseful Sune to unite after all with his daughter.
