Caleb Marr is a man who has come to the inescapable realization that he has failed in all aspects of what it means to succeed or fail in the eyes of society, as he sees these things. His wife never misses an opportunity to reaffirm his total sum as a man is no greater than the meager crops he yields as a "dirt farmer". Any hopes he had to raise a family as a source of pride and joy will never happen either, as his wife saw no pride, no joy..... rather more messes, chores and meals to make with resources they didnt have for themselves, let alone more mouths they would have had to feed. These bitter realizations were too little too late for Caleb. The least he could do is move to Dodge City to see what, if anything might still be salvaged from the life he believes, to that point, he had squandered. Without giving away any of what happens, the story of Caleb is profound as we see it is never too late to "make it count for something". Caleb is a gentleman and a gentle man. He was kind to his beloved dog, called "Dog-Dog-Dog". He found pleasure in time spent with children who needed help with a broken wheel for their little wagon. He defended a lady's honor because it was the right thing to do. He saw the best and the worst in people but never needed a compass to know where true north was as far as right and wrong were concerned. If my review sounds over the top, I can only say I have not done justice to the writer(s) of the teleplay. The actors and dog trainer are superb, as is typical with Gunsmoke. John Dehner was a remarkably gifted and versatile character actor.
