In 1972, deep in the Appalachian wilderness, a bus carrying Catholic school girls and their nun chaperone, Sister Lucy, is lost and stranded in the foreboding woods of West Virginia. The travelers are cut off from civilization, isolated in hostile terrain. The forest harbors dark secrets, and they are not alone.
A clan of cannibalistic mountain men, grotesquely disfigured by generations of inbreeding, lurk in the shadows. Driven to the brink of extinction by their own sterility, they hunt for outsiders to sustain their bloodline, focusing on the busload of women they believe can save them.
The girls, unprepared and terrified, must rely on Sister Lucy's guidance to survive. As the clan launches a brutal attack, the girls are transformed from helpless innocents into fierce survivors. With the relentless cannibals closing in, the battle for survival turns the forest into a blood-soaked battleground where the line between prey and predator blurs as each side fights desperately for their idea of family.
