Gunsmoke S20E02 - A Town in Chains

Five ex-Confederate soldiers have robbed the bank in Dodge City and are on the run through Indian territory, followed by Matt Dillon. The outlaws find abandoned Union military uniforms and disguise themselves as Union soldiers. At the next town, they declare martial law under the guise of an Indian uprising. The outlaws, disguised as Union Soldiers, talk the town's sheriff into getting the townspeople to load all their valuables into the safe at the town bank, which they are secretly planning to rob. When Matt catches up to the outlaws, things come to a head.
