Later, Clint becomes a Pony Express Rider who is attacked by one of the members of the gang that wreaked such havoc in his life when he was a boy. Clint wins the gunfight and captures the gang member, Ace Carter, only to find out as he is transporting him to the police that Ace is none other than his abducted brother, Asa.
