A Danish prince seeks revenge upon the villain who killed the king and his son to usurp the throne.
The mysterious Mr. Steinmetz has acquired the ability to create things and beings by will alone. Only, after a while his creations invariably disappear. He therefore approaches a famous brain surgeon, Max Holst, who he hopes can help him with this problem. When Max refuses, Steinmetz brings his doppelgänger into being to replace him.
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.
