Buck Starrett, Texas ranger, had a reputation for fast shooting and a determination to win against overwhelming odds. He was optimistic when he took a novice ranger to Adobe Flat on the Mexican border, but he was unaware that the grim set-up that awaited them would be his toughest challenge yet. When they plunged into an all-out war with Mexican rustlers operating on both sides of the border, Starrett discovered that this desperate situation was only half the problem facing him. He would have to shoot his way into the crooked situation enveloping Adobe Flat before he could even begin to overcome the criminal element and shoot his way out again.
