Five film students are producing a documentary about the local zoo when suddenly the animals go berserk: The reason is a light ball flying by in the sky and crashing at the horizon. Convinced that they've just witnessed a meteor landing the students follow the trajectory to document the event with their camera. In a forest area they discover a burned crater. Since it's too dark to film they decide to spend the night in their van. The next morning one of them is missing. The remaining students find first a trail of blood and then the torn up pieces of what used to be their friend. Soon they realize that something is hunting them - something that's not from this world.
