Lady Belle Smythe, engagingly played by Joan Marshall, has a gang and a fool proof con. She arrives in a new town on the Stagecoach pretending to be an innocent young widow looking to open a business. Quickly befriending the local Bank Manager, she passes on the details of the bank to her men who arrive the next day to rob it, then it's on to the next town.
With Deputy Johnny away at a Peace Officers' meeting in Cheyenne and Marshal Dan going down with a shot to the shoulder during the shootout it is left to the townsfolk of Laramie led by Slim Pickens and Doodles Weaver to successfully fight off the robbers. Peggie Castle must have loved this excellent, action-packed episode where she twice gets to break out of the lady-like Lily persona: first when she loses her temper at Dan after her new dress is insulted by Lady Belle and second when Dan is out of action, she takes down Lady Belle with a right hook and reveals the cash hidden in her travelling case.
As a bonus Peggie Castle gets to sing a song and she sure looks pretty when asking Dan to a conciliatory lunch of pig knuckles. Kudos to series writer Ric Hardman who slipped one by the censors when Lily protests to Dan that her dress is brand spanking new, he replies that spanking is what it calls for and heads off to her office.
