At the request of gallant Colonel Fairchild (Charles Ruggles) and his lovely daughter Patty Lou (Julie Parrish), Ben Cartwright agrees to arrange a championship horse race. What Ben doesn't know is that the Colonel has fixed the outcome of the race to rid himself of nasty creditor Jack Geller (Skip Homeier). When Ben finds this out he enlists the aid of his son Joe to fix Geller's wagon without harming the Fairchilds. Written by William R. Cox, "Horse of a Different Hue" first aired September 18, 1966.
