Scorched remains that speak of imprisonment and torture... the desert town that faced a disaster of biblical proportions... a rusting cab leway leading to a deadly site in the mountains of southern Africa... vast coastal ruins that reveal a past once wiped from history.

Including an exploration of the claustrophobic prison cells of Devil's Island; Vemork, a vast mountainside complex that held the power to change the world; Salton Sea, where a string of crumbling towns are linked by a toxic secret; and Ralsko, a sprawling secretive base that's been left standing on deadly ground.
