On the streets of Dodge City, Chester talks with Doc about some medical advice. Doc’s words are cut short when a rider goes past, and Doc soberly claims that he’s going to kill that man.
Matt is on the scene to try to get to the bottom of the hostilities. Doc ain’t saying what the grief is, and the miner is just as tight lipped. Later, a gunshot breaks the night time silence. When Clem the miner is shot, Doc is the prime suspect, but he’s also the one who could patch him up if anybody can.
Matt is sure his friend is innocent, but he needs proof to clear him. Doc saves Clem’s life, and Matt’s proof is forthcoming soon enough. But will Doc share his dark secret from his past? Is there a chance the two old acquaintences will make up, and let their old grudge drop?
Note: The pistol Doc is said to be carrying is a Walker Colt. It was the first model that was mass produced, and was the weapon of choice of Texas Rangers as they fought for independence from Mexico. Later, it was the side arm widely used when Civil War generals were young captains, and fighting together on the Mexican border under General Winfield Scott.
