Rough Night in Jericho (1967)

The only business in the Wild West town of Jericho that corrupt sheriff Alex Flood doesn't control behind the scenes is the stagecoach owned by tough-willed widow Molly Lang and her right-hand man, Hickman. Former marshal Dolan, recently hired by Lang and Hickman as a driver, wants to stay out of the mess, but when he sees Flood's henchman Yarbrough assault Lang, he steps up to fight the corruption.
