The year is A.D. 922. A refined Arab courtier, representative of the powerful Caliph of Baghdad, encounters a party of Viking warriors who are journeying to the barbaric North. He is appalled by their Viking customs - the wanton sexuality of their pale, angular women, their disregard for cleanliness...their cold-blooded human sacrifices. But it is not until they reach the depths of the Northland that the courtier learns the horrifying and inescapable truth.
They rise... Out of the flooded streets of Houston, they emerge from plague-ridden waters. Dead. Rotting. Hungry. And as human survivors scramble to their rooftops for safety, the zombie hordes circle like sharks. The ultimate killing machines. They feed... Houston is quarantined to halt the spread of the zombie plague. Anyone trying to escape is shot on sight---living and dead.
