The Guns of Will Sonnett
A Town in Terror (1) (2x17)
: 07, 1969
When Will and Jeff run right into the middle of a deadly cattle versus sheep feud which has enveloped a grazing town, James Sonnett, a hired gun for the sheep ranchers, runs right into a cattleman's hired gun who looks just like him (played by a different actor) -- and gets into a fatal gunfight.
