The Vikings raid the Northumbrian village of Hexham with little bloodshed, as the villagers are gathered for Mass. During the raid, Lagertha kills Knut when he tries to rape her. Back on the beach, the raiders defeat a superior Northumbrian force under Lord Wigea, sent by King Aelle, and return to Kattegat. There, Earl Haraldson has Ragnar, who claims to have killed Knut, arrested and tried at the Thing assembly. The Earl's ploy to bribe Rollo to testify against Ragnar fails, and Ragnar is acquitted. As the raiders celebrate with Athelstan and Ragnar's children, they are assaulted by armed men. Although Ragnar's followers prevail, his companion Erik is killed. https://odysee.com/$/invite/@Vikingsseries:a

Ragnar's warband returns in triumph to Kattegat, where the Earl immediately confiscates the plundered riches except for one piece per man. Ragnar picks the distraught Athelstan and returns home. The monk's faith and his vow of chastity perplex Ragnar, but he, nonetheless, gathers useful intelligence about the kingdom of Northumbria. Based on this new insight, Earl Haraldson authorizes another raid on England. Now accompanied by Lagertha and the Earl's brother, Knut, Ragnar re-embarks post-haste, leaving Athelstan to mind the farm and the children. As the Vikings set foot on English soil, they are met by the local sheriff and a handful of armsmen, who invite the newly landed "traders" to meet King Aelle. Ragnar agrees, but his other warriors' distrust incites a battle in which the Northumbrians are slaughtered. https://odysee.com/$/invite/@Vikingsseries:a

Ragnar and his brother, Rollo, return from a battle in the Baltic lands during which Ragnar has visions of the god Odin and his valkyries. Home again, Ragnar takes his son Bjorn to Kattegat, for Bjorn's rite of passage. Left at home, Ragnar's wife Lagertha quickly dispatches two would-be rapists. While in Kattegat, Ragnar convinces Rollo that raids to the West are worthwhile and possible, thanks to new navigational tools, but is rebuked by his ruler, Earl Haraldson, who continues to order raids into the Baltic; but, also has the upstart, Ragnar, watched. Bjorn and Ragnar visit Floki, Ragnar's friend and a gifted shipwright, who has been secretly building a new type of longship, which they successfully test. Meanwhile, back at home, Rollo makes unwelcome advances on Lagertha. Ragnar has yet another vision of Odin, standing on the shoreline. This convinces Ragnar to finally move on with his plan. https://odysee.com/$/invite/@Vikingsseries:a

Ragnar's embassy to Jarl Borg in Götaland fails, as King Horik rejects a compromise settlement about the contested land. Driven by ambition and jealousy, Rollo agrees to support Borg against Ragnar. In Kattegat, a disease kills many inhabitants, including Lagertha's daughter, Gyda, and Siggy's daughter, Thyri. Lagertha asks the seer about Ragnar and her future but the seer refuses as he only sees misery. Underway, Ragnar meets and is seduced by the princess Aslaug; eventually, she reveals she carries his child. https://odysee.com/$/invite/@Vikingsseries:a
