Deep in the forest, two teens run for their lives with two vulture-like creatures called Geiers hot on their trail. When they hit a river, one of the teens, Steven, slips in and floats away. Before Kevin can help him, he's grabbed from behind by the Geiers who pull him screaming into the woods. Kevin is dragged past a fire pit into a barn, where the body of a young girl is being thrown into the flames. The next morning, we see Steven's lifeless body float down the river and over a large waterfall.
