Louis Theroux spends time with a small and very committed subculture of ultra-nationalist Jewish settlers. He discovers a group of people who consider it their religious and political obligation to populate some of the most sensitive areas of the West Bank, especially those with a spiritual significance dating back to the Bible.

Throughout his journey, Louis gets close to the people most involved with driving the extreme end of the Jewish settler movement - finding them warm, friendly, humorous, and deeply troubling.
