13. The Widow from Red Rock 11/26/1967
Billy Blue Cannon faces possible hanging when he is court-martialed on the charge of killing an army general's son. Billy Blue saves an Indian girl from advances by a drunken army lieutenant, who is killed in the fight. When the girl flees to the Apache stronghold, Buck and Manolito risk their lives to persuade Cochise to release Blue's only eyewitness. Her testimony is discarded when the court learns her release was obtained by a bribe. It becomes obvious to John Cannon that the court-appointed defense is incapable of saving Billy Blue, and John personally takes over his son's defense.
Guest star: Patricia Barry (Mrs. Melanie Cawthorne), Duke Cigrang (Strobe), I. Stanford Jolley (Foreman), Carlos Romero (Romero)
