A buffalo hunter stumbles on the fact that a local man was head of an abusive Confederate prison camp during the war. With tension high, Matt and Festus will try to prevent citizens from taking the law into their own hands. 

After surviving (barely) a bounty hunter's attempt to assassinate him, an outlaw tries to turn himself in to Matt Dillon. But Matt's out of town, and the bounty hunter's companions get to the outlaw first. They aren't so much interested in the outlaw as they are in killing Matt, so they take over the Long Branch and hold everyone hostage. They also get word out to a land baron whose wife the outlaw accidentally killed: come here and pick up the prisoner in return for your gunmen to waste the marshal. The land baron accepts the deal, but the outlaw's girlfriend shoots him as he's about to take the outlaw away. While Doc performs an emergency operation, the land baron's hirelings are torn between their promise to punish the outlaw and their revulsion at the bounty hunters' sadistic leader, who forces town drunk Louie Pheeters to crawl on his hands and knees the length of the saloon to get a drink (which he then refuses in a dramatic sequence). This episode's production number indicates it was actually filmed at the end of the previous season and held up for reasons unknown (it's shown in broadcast order in syndication).
