Pitting the titular Appalachian dwellers (Transformers: Dark Of The Moon's Alan Tudyk and serial television supporting player Tyler Labine) against a gang of judgemental college kids on a camping trip (including 30 Rock's Katrina Bowden as an open - minded beauty thrust into
peril from an unexpected source, and The Uninvited's Jesse Moss as a trigger happy frat boy obsessed
with a previous massacre in the area), it subverts the conventions of the splatter genre to provide a playful paradigm shift of the oft - used (as seen in everything from 2000 Maniacs to The Texas Chainsaw Massacre) evil hillbilly premise, proving that appearances can be deceiving as well as deadly.
