Cavalcade of the West on AllMovie

In his final Western for low-budget Diversion Pictures, veteran cowboy ace Hoot Gibson plays a pony express rider who discovers that his worst enemy is his own long-lost brother. As a child, Clint Knox (Jerry Tucker), and his mother Martha (Nina Guilbert), escaped a gang of bandits who killed Mr. Knox Steve Clark and abducted Clint's brother Ace (Barry Downing). Eleven years later, the adult Clint (Hoot Gibson), now a pony express rider, is ambushed by Ace (Rex Lease), a road agent who also robs a stage carrying Martha and pretty Mary Chrisman (Marion Shilling). In the ensuing gunfight, Clint's life is saved when his pocket bible stops one of Ace's bullet. But when Ace, now Clint's prisoner, recites an illegible inscription in the book, Clint realizes that he is his brother. At the trial, Clint successfully convinces the jury to acquit Ace because of the young man's harsh upbringing in the hands of his kidnappers.
