Hang 'Em High (1968)

In Oklahoma Territory in 1889, retired lawman Jed Cooper drives a small herd of cattle across a stream. A posse of nine men – Captain Wilson, Reno, Miller, Jenkins, Stone, Maddow, Tommy, Loomis, and Charlie Blackfoot – surround him and demand that he show them a receipt for the cattle. After learning the man from whom he bought them was a robber who had impersonated and killed the owner, Cooper explains that he knew nothing about the murder; but only Jenkins expresses doubts about his guilt. After Reno takes Cooper’s horse and saddle and Miller takes his wallet, the men hang him from a tree and ride away.

Shortly afterward, Deputy U.S. Marshal Dave Bliss rescues the half-dead Cooper and takes him to Fort Grant, where the territorial judge, Adam Fenton, determines that Cooper is innocent, sets him free, and warns him not to take his own revenge. As an alternative, Fenton offers Cooper a job as a Deputy U.S. Marshal. Cooper accepts, and Fenton warns him not to kill the lynchers, but to bring them in for trial. While picking up a prisoner, Cooper sees his own horse and saddle in front of a local saloon.
