The Green Mile tells the story of two men, a prison guard and his new death row inmate, and their suddenly intertwined lives. What would it be like to walk those last 40 yards to the electric chair, knowing you were going to die there? What would it be like to be the man who had to strap the condemned man in or pull the switch? What would such a job take out of you, or even add? The Mouse on the Mile: Cold Mountain Penitentiary has been home to many troubled souls. E Block, where the electric chair waits for those who must pay the ultimate price, has been home to the most troubled of all. And here, not all the evil is behind bars. Sometimes it carries a gun and wears a badge.
