On the day he gets married and hangs up his badge, Marshal Will Kane is told that a man he sent to prison years before, Frank Miller, is returning on the noon train to exact his revenge. Having initially decided to leave with his new spouse, Will decides he must go back and face Miller. However, when he seeks the help of the townspeople he has protected for so long, they turn their backs on him. It seems Kane may have to face Miller alone, as well as the rest of Miller's gang, who are waiting for him at the station. Written by Man_With_No_Name_126
The summer temperature soars, as does the tension during the hour before the arrival of the midday locomotive that will bring with it a vengeful gunslinger to settle an old score with the Marshal: who will soon discover who his friends are.
Vengeance, treachery, ignorance, justice and survival - concentrated around the barrel of a gun.
