Flathead Valley, Montana. Sitting just outside Glacier National Park, this secluded corner of the nation is dotted with snow-capped peaks and striking vistas. But over the last decade, this idyllic setting has become home to an increasing number of white supremacists and anti-government radicals. Some of them envision the creation of an all-white homeland in this remote area, while others see it as a modern-day Alamo where they can escape from the invasive reach of the government. Harris travels to Montana to see for himself what is happening in Flathead Valley, and how communities are reacting to this convergence of extremists in their own backyards.
