In Idaho, Louis meets military enthusiasts and right-wing patriots who are preparing for a global catastrophe, including trips to survivalists' store Safetrek and a mountain refuge for conspiracy theorists called Almost Heaven.
Louis also visits the Aryan Nation Church and helps to build a straw-bale home. The episode focuses on the survivalism movement and communities formed around it.
The fact that several self-proclaimed survivalists were also hippies and environmentalists is a recurring theme.
Louis spends time with groups of (mostly) politically extreme people in the North West of America. The focus is on families and groups (or a horrific neo-nazi church in one part) which believe in and prepare for a 'New World Order' - a very interesting and funny documentary.
