Settled in the south Ural region in Russia, the film tells the story of people living in one of the most radioactively contaminated spots on earth. Unknown to a wide public, this region was repeatedly irradiated by different accidents of the Mayak nuclear facility, which was the first plant for the production of fissile material for nuclear weapons in the Soviet Union and is still in operation. The film captures a danger that is neither perceptible nor visual and the strength of people who have to cope with it.
