Yuma

In this Western adventure, Dave Harmon (Clint Walker) is hired by the governor to clean up rough and wild Yuma, but the town's orneriest citizens set out to destroy the lawman's reputation and get him fired from his new job. Harmon takes his job seriously, but after he shoots a troublemaker, he finds himself up against the dead man's powerful brother, Arch King (Morgan Woodward). Barry Sullivan and Edgar Buchanan co-star.
