The Deputy (1959)

Season 2: Episode 4

Well-to-do Elmer Jackson is murdered and evidence points to his nephew, Phil, who has fled town. Clay McCord suspects Phil's sister, Martha, knows his whereabouts though she denies this. Clay secretly follows Martha out of town but she knocks him out with a rock to the head and rides on to a cabin where she meets her lover, outlaw Tweed Younger. Tweed killed Elmer Jackson but made it look as if Phil had. Phil's now a prisoner in the cabin. Double-crossing Martha shoots Tweed and is about to kill Phil when McCord arrives on the scene.
