A Western Gentleman

A mysterious stranger happens upon the town of Burlton, Arkansas and is greeted with hostility by local law enforcement, because the community has shut its borders to outsiders, for public safety. The man is apprehended and embodies some strange contradictions. He dresses as a British aristocrat, talks with a southern accent, exhibits keen gun skills, and outsmarts the local powers-that-be at every turn.
He also lives by a code: the code of a gentleman, which he enjoys vehemently teaching to the local townsfolk whenever the need arises. As the man familiarizes himself with the town, he sees corruption and exploitation in every facet of life there. He sees a stranglehold on the townsfolk coming down from those in power, keeping those below them in place. The mayor, the sheriff, the deputies, the priest, the landlord, the doctor and the banker all belong to the same family that has insinuated themselves into positions of power and taken control.
Tensions reach a boiling point as the dapper stranger challenges the control of the Behen clan, resulting in his apprehension, until the stranger reveals himself to be a U. S. Marshall who didn't happen on the town by chance. In reality, the peculiar stranger has a bloody connection to the past of the corrupt clan ruling the town. In spite of his dandy demeanor, the well-groomed stranger may have no other option but to dispense justice to the lecherous leaders of Burlton from the barrel of a six-shooter.
