Scotland, 1000 AD. A world torn between the brutality of the past and the civility of the future. A mute Scandinavian savage known only as “One Eye” (Mikkelsen) is kept as a animal and only bought out of his cage by his owner to fight for money. Aided by Are, a boy slave, One Eye slays his captor and together he and Are begin the long journey home. En route, One Eye and Are team up with a band of Viking Christian warriors, who have set their sets on conquering Jerusalem. Their ship, however, is soon engulfed by a seemingly endless fog. When it finally clears, they find themselves lost and in an unknown land. As the new world reveals its secrets and the Vikings confront their terrible and bloody fate, One Eye finds himself on a journey of a much darker nature.
