Cheyenne

Pat Keogh is a bank robber and killer who, when the episode begins, has just killed a man and Cheyenne has been accused by a group of vigilantes. Keogh rescues Cheyenne, admitting to him that he was the guilty party, and he cuts Cheyenne in on the bank robbery he's about to make in Red Rock with the help of two accomplices. Cheyenne meets a marshal friend who is trailing Keogh and enlists Cheyenne's help in stopping Keogh. Cheyenne foils the plot, but not after a lot of gunplay.
