Avsnitt 23

With unprecedented access, this documentary looks into the hidden world of one of Russia's most impenetrable and remote institutions - a maximum security prison exclusively for murderers. Deep inside the land of the gulags, this is the end of the line for some of Russia's most dangerous criminals - 260 men who have collectively killed nearly 800 people . The film delves deep into the mind and soul of some of these prisoners. In brutally frank and uncensored interviews the inmates speak of their crimes, life and death, redemption and remorselessness, insanity and hope . The film tracks them though their unrelenting days over several months, lifting the veil on one of Russia's most secretive subcultures to reveal what happens when a man is locked up in a tiny cell for 23 hours every day, for life. A startling insight into inscrutable minds and the forbidding world they have been condemned to.
