Times have been tough for King Knut's Viking settlement. The only hope for his people is the raiders that have been sent out on ships to pillage and bring back goods. When they find a seemingly empty ship in the distance and excitedly board it, however, they accidentally unleash a zombie plague that they'll take back home with them, forcing their settlement to a fight to the death with those horrific monsters. Will the settlement be able to survive, or will this be the beginning of the end for their people?
