Sylvain, an engineer come vigilante inventor, has constructed a device. It is close to functional, but something isn't right. His wife, Mary Anne, is running out of patience. She loathes the woods in which they live and yearns for a return to the city. Problems arise when their already tense situation is exasperated by the appearance of shadow beings, which torment them during the night. Sylvain slowly comes to realize that this is not a localized event and some greater scheme might be at work. From the meth producing hillbillies on the mountain top to the corrupt lawman, Sheriff Donnelly, no one can escape the reach of the shadow people.
