Query: Film Shot So Natural and Real.

Excellent film of an Alaskan tribe survival in their natural territory. They respect their elders. The eldest son must hunt for food and get along with other tribe's they meet. But some tribes are called "strangers". They try to steal someone's dog sled, food or kill for what they want. The Fast Runner can keep it all together. An evil tribe tries to kill by stabbing the tent he and another man is sleeping in. Naked, he escapes and runs for his life and even appears to run on water while enemies fall through. This film, shot on video, also deals with evil spirits, love, death and leadership. But mostly, the family stays together no matter what. There are scenes of full frontal male nudity, female nudity, sex and simulated violence.
