Behind Bars: The World's Toughest Prisons: Season 2, Episode 3

2 - 3: Colony 100, Kharkiv, Ukraine

Colony 100 - Ukraine's prison for hardened criminals. All those behind the walls of this Soviet-built prison have either already done time in at least three other Ukrainian jails, or they have committed crimes so heinous that they will never again leave their 100-square-foot-cell in the maximum security wing. The prison is marked by an omnipresent hopelessness.
