Askeladd and his men continue their march to escape from Thorkell. However, their march comes to a halt at the Severn River. Askeladd hands a letter to an old man operating a ferry across the river and tells him to deliver the letter to the other side immediately. As soon as he hears the addressee’s name, the old man sets off in his boat.

Askeladd and his men change course and decide to return to Gainsborough, by crossing through the Earldom of Mercia in the midst of a harsh snowstorm, where the main army of Denmark awaits. The men spot a small village in the blizzard and make their move.

Askeladd and his men are attacked by the English army in the village where they had planned to camp during the winter. Askeladd captures their captain and interrogates him to find out how the English knew where they were, and discovers that Thorkell is fast approaching. The news of Thorkell's arrival sends waves of shock among Askeladd's followers.

Thorfinn and Thorkell agree to have a duel over the fate of Askeladd. Thorkell looks forward to facing off against Thors’s son, Thorfinn, and asks him what a true warrior really is. Meanwhile, Canute is suddenly ambushed while he attempts to escape, and has a dream about a certain individual.

Thorfinn suffers a serious injury in his fight against Thorkell. Thorfinn is told to think about what he has to do to beat Thorkell. Askeladd treats Thorfinn’s wounds so that he may fight again someday, and proposes a joint strategy to help the two of them survive longer.

Einar and Thorfinn are told to convert a wild forest into a wheat field; and if they succeed, they will have the chance to buy their own freedom.

Thorfinn and Einar are working themselves to the bone to clear the forest, but there's only so much they can do without the help of horses.

Thorfinn wakes up in a peaceful place and he sees his father again. But then things quickly turn dark, and Thorfinn must face his painful past.

While in Jelling, Ketil, Thorgil and Olmar meet a man named Leif Erikson who is searching for Thorfinn, the son of his close friend.

Arnheid comes to the fortress where Gardar is imprisoned. She wants to see her husband and treat his injuries.

As Snake intensifies his search, Arnheid tells Einar and Thorfinn everything she's done. Knowing the risks, Einar and Thorfinn offer to help her.

Amidst the confusion of a peasant uprising, Thorfinn and the others try to escape, carrying a severely injured and pregnant Arnheid.

The battle has left heartbreaking casualties in its wake. Though Thorgil and Ketil's wife want to continue the fight, Canute demands their surrender.

Snake tries to put a stop to it, but Thorfinn insists on receiving all 100 blows from Canute's brutish guard Drott, shocking the rowdy onlookers.

Thorfinn and Einar have said their piece, but Canute stubbornly refuses to give up Ketil's Farm. Then, Thorfinn breaks the standoff with a decision.

At long last, Thorfinn returns to Iceland and finds a moment of happiness, reunited with his loved ones. But soon, he opens up about his next journey.
