They remain in the cells almost all the time and may only leave for yard time twice a week. They also live under the sway of a gladiatorial code. They must fight each other for food, for status and often just to pass the endless hours of confinement. Trips to the infirmary are a daily occurrence and inmates are viciously attacked and beaten but the guards say they are powerless to end the abuse This trailer is the property of the BBC.
