The movie starts with a guys head being chopped off, this happens in the very first scene so i guess it's a reminder of the movies R certification. Some students go on a expedition or as their teacher prefer to call it a field-trip. Close to their destination the car breaks downs and they go to a near by gas station, there they come across an native-American old man that warns them about the hills, about the killings that went on in the past. As you can expect, they aren't concerned with the warnings and continue their search for artifacts at what they now know to be an native-American burial ground. After a successful afternoon collecting artifacts, one of the guys is possessed by an native-American spirit, that gradually transforms him physically... let the scalping begin.
i found the gory scenes by far the best aspect of the movie. the location is also nice, reminding me of movies such as the "hills have eyes", the hot, dry california desert helps create some tension, the vulnerability of the open spaces. there's not much acting going on but the actors did a reasonable job. a good way to spend 80 minutes, if you're a horror fan.
