There is something lurking in the trees.

A winter storm has buried North Dakota in snow and ice. With accidents being reported across the region, Deputy Ron Weller must patrol along the main road through a normally tranquil forest in Beeman County. The night grows menacing as he discovers vehicles that have been run off the road, their drivers mysteriously missing. Strange tracks lead through a region of thick forest known as Devil's Rock. There, Weller makes a horrifying discovery.

A monster has awakened. Its hunger is insatiable, and its ferocity has no limits.

Protected by an armored exoskeleton, the beast is relentless in its pursuit of prey. It must feed or face starvation. What has started as a search for a missing driver has now become a fight for survival, as Ron Weller is hunted by THE BEAST OF DEVIL'S ROCK.
