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.

Einar lives peacefully in northern England with his mother and sister, but then one day, their village comes under attack.

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.

Snake strikes quickly, surprising Thorfinn with his speed and agility. As he lies wounded, Gardar thinks back on the life he shared with Arnheid.

After returning home to his farm, an exhausted Ketil starts searching for Arnheid, only to find out what happened in his absence.

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

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.
