在俄罗斯的深处，有一个看不见的城市，里面住着成千上万的男人、女人和孩子，他们住在武装警卫监视的铁丝网后面。他们说他们是世界上的核盾牌和救世主的创造者。他们被告知每个人都是敌人。在这个隐秘的世界里，一位母亲冒着生命危险带我们进入俄罗斯最大的核城市。

  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.
