A couple goes to a secluded and quiet lakeside for a vacation away from the hustle and bustle of the city, and unexpectedly conflicts with a group of runaway youths. When the two try to cross the jungle to seek help in a nearby town, they are brutally attacked by the youths. James Watkins, a new British talent, wrote and directed his debut feature film, which features a realistic story, extreme fear that strikes directly at the heart, and a bloodthirsty rating that rivals "The Texas Chainsaw Massacre", thoroughly testing the audience's cardiac strength.
