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.

Louis spends time in one of the most notorious sections of Miami County Jail: the fifth and sixth floor of 'Main Jail', where many of the most volatile inmates are incarcerated.

Held in large cage-like dwellings for up to 24 men, the inmates have developed a strange and violent jail culture. The men - who remain in the cells almost all the time and may only leave for yard time twice a week - live under the sway of a gladiatorial code. They fight each other for food, for status, and often just to pass the endless hours of confinement. Trips to the infirmary are a frequent occurrence as inmates are viciously attacked and beaten, but the guards say they are powerless to end the abuse.
