Welsh noblewoman Morwen Angmire awaits the arrival of her betrothed, the Marquis Delmore Le Chevreaux of France. But before the Marquis can arrive to claim her, the Northmen raid her father's keep and take her and several other women away to the harsh, cold north, where Morwen is claimed by Bjorn Halden, the devilish but handsome son of the village chieftain.
As winter comes and sailing is treacherous, Morwen must learn to live as a Viking, while to the south some dark horror has arrived in Wales with the French nobleman. Livestock and peasants are found ravaged by what seems to be a large wolf, and the people live in fear.
When the monstrous Marquis comes to claim the woman he was promised, he must battle the valiant Viking. Who will win the heart of the bold bounty?
