In flashback, the elderly Paul Edgecomb tells his friend Elaine about the summer of 1932 when he was a corrections officer in charge of Death Row inmates in Louisiana's Cold Mountain Penitentiary. His domain was called the "Green Mile" because the condemned prisoners walking to their execution are said to be walking "the last mile"; here it is on a stretch of green linoleum to the electric chair.
One day, a new inmate arrives, John Coffey, a seven-foot-tall black man convicted of raping and killing two young white girls. Upon being escorted to his cell, he immediately demonstrates "gentle giant" character traits: keeping to himself, fearing darkness, and being moved to tears on occasion. Soon enough, John reveals extraordinary healing powers by healing Paul's urinary tract infection and resurrecting a mouse. Later he also heals the wife of the warden, who is terminal.
It turns out he is also innocent of the crimes he was convicted of. The real perpetrator was another death row member called Bill "Wild Bill" Wharton, who he killed for that. Still he was executed for them, partly because he wanted it. He was tired of living in this world with his heightened senses and see all the uglyness in it.
Sixty years have passed since then. Paul is a very old man now. Still he is quite healthy. He is convinced, that it is a byproduct fo John´s healing and asks himself, when he will die next, especially after having to think about the mouse John healed and that is still alive.
