Stage to Blue River

Marshal Whip Wilson and his pal, Texas, come to the aid of Joyce Westbrook after her father is killed by henchmen of a mysterious Mr. Blackwell, who is after the stage line contract left to Joyce. She tries to get a government mail contract, but one of the conditions is that her stage line must be proven safe.
