Noah Beery Jr. guest-stars as Johnny Mule, on trial for the murder of David Lowdon. Typically, Hoss Cartwright casts the vote which deadlocks the jury, convinced that there is reasonable doubt regarding Johnny's guilt. But when Johnny breaks out of jail rather than face a retrial, Hoss must come to grips with the possibility that his instincts were wrong. Also in the cast are such powerhouse performers as Coleen Gray, Lee Patterson, Jack Ging and John Archer. Originally titled "The Trial of Johnny Mule", this episode was written by Joel Murcott, and first aired on February 25, 1968. ~ Hal Erickson, Rovi
