In the year 1002, the war between England and Denmark was intensifying. One day, the Jomsvikings pay a visit to Thorfinn's village in order to bring back Thors, their former commander, to prepare for the impending battle. Thors is forced to join the war in order to protect the villagers from being taken hostage, and must face his accursed past in order to save his family and his village.

Askeladd, the leader of a Viking army of a hundred men, receives orders from Floki of the Jomsvikings to kill Thors, who was once known as the Troll of Jom. However, the villagers, completely unaware of the order, buzz with excitement as they prepare for their first battle. Thorfinn also joins in the excitement. Thors and his men are about to embark on a difficult sea journey to England.

Thors and his men fall for Askeladd's trap and faces a dangerous situation, but Thors defeats many of Askeladd's men with his overpowering strength. However, Thors knows that it will be difficult to save everyone, including his son, who've been living in a peaceful village their entire lives, and makes a tough decision.

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 crosses the river and escapes from Thorkell into Wales with Canute. However, Askeladd’s men are ambushed by a group of soldiers hiding behind the boulders at the border of the kingdom of Brycheiniog. Askeladd attempts to negotiate with their messenger and reveals his plan.

After losing Canute, Thorkell decides to halt his advance in central England. Thorkell hears that the end of the war between Denmark and England is near, and bemoans the end of the war. However, he later gets wind of an interesting piece of news.

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.

Askeladd's men continued their march to escape Thorkell. However, Torgrim and his friends were hatching a plot to switch sides and join Thorkell, taking Canute with them. Torgrim finally launches his rebellion and corners Askeladd, negotiating with him to hand over Canute, then Thorkell arrives in the midst of the confusion.
