The Virginian Season 2 Episode 13 Siege

Trampas hits it lucky in an all night poker game in Medicine Bow and walks away with big winnings. He decides to take a vacation, repay several debts he owed from years back, and see a girl he has fond memories of in Logan, New Mexico. Many of the locals are surprised and happy when he pays his debts but Duke Logan is not happy to see Trampas. Duke wants him away from his sister Carole who is married to the city marshal Brett Cole. When Trampas goes to visit the family he worked for, he finds they have been murdered and their home ransacked. He tracks down the Commancheros, kills one, and brings the other two to the Marshal. He learns that the area is under control of Commancheros and that the city residents want the two men released. Duke and Carole try to convince Trampas to withdraw his complaint against the two men but the Marshal backs Trampas against his wife's wishes. When the town removes the Marshal all seems well until the Commancheros tell the people to leave the streets as Trampas prepares to leave town.
