Flanking the course of the river Techa and extending some 23,000 square kilometers, this region has the highest radioactive contamination in the world. There, on September 29, 1957, a nuclear accident happened, covered up by the Soviet regime for many years. Local residents were not warned because of the secrecy of the Soviet regime. The accident occurred at the nuclear facility called Mayak, the first plant that produced fissile material for nuclear weapons in the Soviet Union. Next to Chernobyl and Fukushima, the “Kyshtym disaster” is considered to be the third most serious nuclear accident in history. The film is about the people who still live in the region. Black and white images of deserted landscapes, capture the invisible danger still threatening their residents today.
