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

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.

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

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

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.
