In 8th-century Europe, a clash of cultures and religions inevitably leads to a clash of swords. This harsh, changing world suits Björn the Beautiful, who has a single passion: violence. His bloodlust led to his exile from his native land, and it's his bloodlust that brings him back. For Harald, it's the season of Jul and he's about to marry the gorgeous Lina. The festivities are interrupted by the arrival of Björn and his troops. With his people either slaughtered or enslaved, Harald begins a forced march with the other survivors. He wants revenge, but he must be patient like the serpent: know when to sleep, and know when to strike.
