The Deputy (1959)

Season 1: Episode 6

While Chesley Vantage eagerly greets the arrival in Silver City of his son, Brad, who's been studying in Kansas to be a veterinarian, word reaches Deputy McCord that a gunfighter is also on the way from Kansas, apparently to settle a score. McCord soon learns that Brad acquired his vet training while serving time in a Kansas prison. He also learns that the gunfighter, Jim Stanton, wants to kill Brad because he mistakenly believes Brad warned authorities about a planned prison escape. McCord spares Brad from Stanton's wrath by coming up with a ruse to put Brad in jail. Then McCord kills Stanton in a barroom shootout. Brad's now free to set up his practice and his father, himself a reformed outlaw, is none the wiser about his son's criminal past.
