The story, based on an ancient legend, concerns Hagbard, the son of a slain Norse king. Seeking revenge against the rival clan responsible for the killing, Hagbard calms down long enough to establish a truce. He also falls in love with Signe, daughter of his onetime enemy. Signe’s former beau, sizzling with jealousy, breaks the truce and makes it appear that Hagbard was responsible. The young prince escapes, but returns disguised as a woman to his beloved Signe.
