During a winter storm, a ravenous beast preys upon the people of a remote town and a pipeline construction company. Among them, a predatorial psychopath welcomes a master as cold and dark as his heart. Following a trail of carnage, retired police chief Sam Larsen, along with a hellbent group of men and a corrupt sheriff, desperately try to stop the beast before its contagious hunger spreads to others. A young mother, trapped inside her isolated home with her children, must do everything in her power to survive the night.
