A dimensional gateway opens in the sky and from there, come five hideous creatures. Four arms and built for power and speed, these are the Grakken...and they are pure killing machines and under the control of King Zombie. The group, camping in the wilderness, is surprised as Deake crashes their camp. Deake fills them in with what he knows and explains that he has the power to close the gateway and end the zombie menace. Continuing on their journey the teens come across a family living in a secluded farmhouse.
