In the first three episodes of Season 2, Ragnar Lothbrok is thrust into a brutal conflict that threatens both his family and his ambitions. Fighting alongside King Horik against Jarl Borg, he is forced to confront the ultimate betrayal when his own brother Rollo stands on the opposite side of the battlefield. But victory brings little peace. Princess Aslaug arrives in Kattegat carrying Ragnar’s child, shattering his marriage to Lagertha and dividing his family just as Ragnar’s dreams of returning west begin to grow.
Ragnar is Earl and prepares a new expedition to England. A violent storm scatters the Viking fleet and drives the survivors onto the shores of Wessex, where they encounter a formidable new ruler, King Ecbert. Raids, ambushes and bloody clashes mark the beginning of a dangerous struggle for power, while Athelstan’s knowledge of England becomes increasingly valuable. Yet the greatest threat may be waiting at home: as Ragnar pushes deeper into Wessex, the embittered Jarl Borg turns his attention towards Kattegat. These opening episodes launch the season with brother against brother, Viking against Saxon, and ambition, loyalty and revenge threatening to tear Ragnar’s world apart.
