prisons are like cities behind walls. if that metaphor were applied to alabama's holman correctional facility, inmate, robert, would be abouteet long by three feet wide. >> this is home. bed to bed. right here. each one of these beds is like having a house in a subdivision out there on the street, only no walls, no doors, no privacy, so you just kind of ignore what's going on next door to you. >> after 20 years of incarceration, 17 served at holman, teter has developed an appreciation for simple routines. >> cup of coffee. first thing. cup of coffee and a cigarette. that's it. that's every morning. then, you know, comb your hair, get dressed, go outside. there is no such thing as a holiday here. there's no christmas. there's no tree. every day is the same. when you get up, it's the same people, the same thing, the same rat race, and there's no relaxation. >> at the time of our shoot he still had ten years left on a 30-year sentence for some very serious convictions. they include sodomy, public exposure and enticement of a child. >> robert was one of those inmates who was adamant he was falsely accused, falsely convicted. >>
