As Thorgrim struggles to keep his men alive, his eldest son Odd leads the resistance to King Halfdan's ruthless attempts to expand his rule over Norway. When a plan to bring Halfdan to heel goes terribly wrong, Odd alone is taken prisoner, and brutally punished as an example to those who would defy their king. But Halfdan's brutality does not cow the freemen: rather it stokes their anger into a red-hot rage that only freeing Odd and extracting further vengeance can cool.
