Legendary gunslinger Jim Bowie (Macdonald Carey) is sent to the remote town of Crooked Tongue, where he and local Daniel Seegar (Will Geer) struggle to arrange a friendly treaty with Quisima (Pedro de Cordoba), the chief of the Comanche tribe. When the vicious Stacey Howard (Charles Drake) -- an opportunist with plans for an illegal silver mine -- and his barkeep sister, Katie (Maureen O'Hara), catch wind of the treaty, they plot to break down relations between Bowie and the Comanches.
