Nine college students embark on a relaxing weekend vacation in the mountains of Northern Arizona. When stopping for gas on the way up, the students are warned of the fate of a similar group of students who vanished from the cabin in the nearby mountains years before. The students pay no attention to what they think is an attempt by local citizens to frighten naive visitors. Unfortunately for them, the strange attempts don't stop when they arrive at the cabin. Soon everything that the students think is real will be tested as they fight unimaginable evil that lurks in the surrounding forest.
