Hagbard and Signe (1967)

Seeking revenge against the rival clan responsible for the killing, Hagbard, the son of a slain Norse king, calms down long enough to establish a truce. He also falls in love with Signe, the daughter of his one-time enemy. Signe's former beau, sizzling with jealousy, breaks the truce and makes it appear that Hagbard was responsible.
