Project Arrowhead, a military experiment gone wrong has opened an inter-dimensional rift, setting loose unthinkable creatures in the town of Maine. When a thick fog descends upon a rural community and claims the lives of anyone unfortunate enough to be caught outside, a small band of survivors seeks refuge in a local grocery store. Now trapped in a darkened cloud of pure horror, the frightened denizens of the town are forced to fend off an advancing horde of murderous monsters.

Note: You're a powerful angel.
