Six months' worth of food stocks, off-grid energy sources, weapons stashed in bunkers. Since the 1960s, thousands of survivalists have been preparing for the end of the world as part of a militaristic movement trained to survive war, epidemic or natural disaster. Mathieu Burgalassi succeeded in infiltrating this movement and delivers an account as informative as it is fascinating about a heterogeneous and in many ways quite ordinary group of people, fed on anxiety-provoking political discourse, obsessive militarism, and racism. Determined to protect themselves at all costs, they have been at the origin of numerous terrorist attacks against "non-whites" and the "Arab-Muslim invasion."
