Bonanza
The Trail Gang
S2 E11:
About to set out on a cattle drive, Ben hires a young drifter named Sam Jackson as one of his drovers. What he doesn't know is that Jackson is really outlaw Johnny Logan, who signed on to the drive because he knew it was going to pass near the town of Waycross, and Logan is determined to kill the Waycross sheriff--who is his father.
