Thorfinn, a boy living in Iceland, longs for adventure and is eager to know more about the world. He dreams of a land of paradise called Vinland that he hears about from the adventurer Leif, while he leads his peaceful life with this father Thors, a former warrior. One day, Thors saves a runaway slave and sets a series of events in motion. This is the story of a true warrior in an age of turmoil.

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.

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.

The farm guards convince Ketil’s 17-year-old son that he needs to make his first killing to become a man.

After everything that happened, Einar asks Thorfinn if he's ever fought in a war — and if he's ever killed a man.

After the sudden turn of events, young Canute must rise up to claim the throne to a kingdom much reduced and under attack.

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.

Finally, after three long years, Einar and Thorfinn chop down the final tree in the forest. With hope in their hearts, they talk about the future.

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

Olmar feels insulted by Canute's messenger and, encouraged by his older brother Thorgil, takes matters into his own hands.

A runaway slave appears on Ketil's farm, claiming to be Arnheid's husband. But before he can free her, he's confronted by Snake.

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

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

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.
