Ragnar (Travis Fimmel), a would-be Viking chieftain, longs to fulfill his destiny as an explorer and conqueror, alongside his ambitious brother Rollo (Clive Standen) and loyal wife Lagertha (Katheryn Winnick). But as Ragnar leads daring raids in distant realms across the ocean, treacherous forces in his Norse homeland conspire against him. Faced with shocking betrayals and the temptations of a mysterious seductress, Ragnar must wage war on the battlefield -- and within himself -- to protect his freedom, family and life.
