For the Service (movie, 1936)

Cowboy star Buck Jones made his directorial debut with the Universal western For the Service. 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 (Clifford Jones), the son of commanding officer Captain Murphy (Edward Keane). 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 (Fred Kohler) and his gang.
