Jones is cast as Indian scout Buck O'Bryan, trying his best to keep the peace between the Native Americans and a government outpost. O'Bryan is replaced by George Murphy, the son of commanding officer Captain Murphy. Obviously unqualified for his job, Murphy proves himself a coward and a weakling, forcing O'Bryan to take over when the fort is besieged by outlaw Bruce Howard and his gang.
