Lydie Jean-Dit-Pannel, haunted by her stay in the Fukushima region, realizes a committed poetic video facing risks and disasters related to the military and civil use of the nuclear power. As a vector of her story the filmmaker uses the character of ‘‘lady butterfly‘‘, which she was working on for the last 10 years, and to whom the other heroine, iconic Psyche, will offer an ironic and poetic guidance. The testimony is a lonely, absurd and alarming journey through the nuclear landscape: the region of Fukushima, Los Alamos, White Sands Missile Range, Nevada Test Site, Hiroshima, Chernobyl, Pripyat, Bure and Valduc.
