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