As in the outside world, there is a "system"; and just as on the outside, there is accommodation, honesty, cynicism, violence and all the other factors that make up our society. Three new convicts act as the catalyst for the events that follow; a college teacher, convicted of accidental manslaughter; a young man, sentenced for possession of marijuana; a new guard, interested in changing the system. Inside prison, the 'establlishment' presents itself. The warden doesn't want to rock the boat of the small society within prison walls.
