The people we now call Vikings were among the greatest explorers, traders and adventurers the world has ever known. This is the story of one of their greatest. Sigurd Saemundsson, who through a combination of determination, skill and luck - good and bad - travels far beyond the edges of the world as his people knew it. Facing trials of nature, weather, disease, and warriors unlike any they've ever known, Sigurd and his crew leave their mark across the globe on their way into legend. A tale of bravery, determination, love and tragedy, lost to history. Until now.
