Deep in Russia, there is an invisible city that houses thousands of men, women and children who live and work behind double barbed-wire fences monitored by armed guards. They are told that they are the creators of the nuclear shield and saviors of the world. They are told that everyone is an enemy. In this hidden world, a mother risks her life to take us inside Russia's largest nuclear city.

A number of people featured are not identified for reasons of personal safety. There is a relocated man, a 'chocolate factory' worker & a woman with many dead relatives who are all interviewed anonymously in 2004 archival footage. There is also a male resident with his face blurred, a male nuclear scientist who never faces the camera and four different clients (three women and one man) who all remain anonymous. See more »


At around 43:40 into the documentary, the second lake identified as "Lake Irtyash" appears to actually be Lake Karachay (which as of 2017 has been completely filled in). The dump truck dumping shown was likely not dumping solid radioactive waste as implied, but was part of the effort to fill in and cover the lake to prevent radiation from escaping. See more »


Herself (human rights lawyer): When someone goes public, it's much easier to declare him an enemy and fight him, instead of trying to change something in the system.

Everyone should see this film. It's a reminder of how people who live in comfort will turn a blind eye to injustice until they are in a survivalist situation themselves. Extremely eye opening and full of information, history, and heart. The main character was an inspirational figure to follow. After watching, I am in awe, disgust, and also full of hope. Environmental and social justice change is not an option anymore, it's a necessity.
