850 CE - Alba, present-day Scotland.
Night. A storm rages on the Great Sea and a Viking drakkar is shipwrecked against the cliffs. The only prisoner on the ship, a Northman, miraculously manages to escape. Fleeing from its past, from unforgiving nature and armed only with luck, the man moves into the clearings of the coast. A foreigner and hated in this land, the skilled Viking warrior will clash with the inhabitants of Alba, while a powerful witch watches him. Fighting for his life... surviving for revenge. A Northman.
