Four women who are electro-hypersensitive — a rare condition where people find themselves acutely intolerant to electromagnetic fields including cell phone signals and WiFi — are driven deep into the French Alps in search for remote underground shelters. Now struggling to survive on the fringes of society, their lives teeter between a primitive existence in nature and post-apocalyptic science-fiction. Because of their extreme condition, their way of life has never been photographed — until now. Zone Blanche is a film without electricity.
