Day of the Survivalist.

Vietnam vet leaves the ugly congestion of Los Angeles and moves north to the "paradise" of rural Oregon. He is soon befriended by a group of hardcore paramilitary survivalists, who try to bring him into their circle of righteous Armageddon-ready warriors. Put off by their extreme views, he refuses their offer and, now knowing too much, becomes the target of their aggression... fighting to survive against the odds in the wilderness.
