City 40 (2016)

Plot

Deep within Russia lies Ozyorsk, a secretive Soviet-era city shrouded in mystery and security. Surrounded by barbed-wire fences and monitored by armed guards, this isolated community houses thousands of residents. Nestled in the Chelyabinsk Oblast, it is notorious for being one of the most polluted areas globally and serves as a significant repository for nuclear materials. Known only as City 40, the city's existence is largely unknown to the outside world, raising questions about the lives of those who inhabit this hazardous environment.
