Hunted by raiders, a band of crusading knights escorting the holy grail are forced into a forbidden valley of black death. What they discover is far more terrifying than the plague. Overrun by hordes of flesh-eating zombies, their only chance for survival is to hack and slash their way to freedom.

A giant beanstalk brings Jack to a land in the clouds filled with snarling, evil beasts. When the creatures make their way to the ground, Jack must figure out how to get back down before they destroy earth and everyone in it.
