Undercover Texas Ranger Walt Slade, known as El Halcon — The Hawk — is heading towards the border town of Cholla to investigate some trouble attributed to a group called the Cholla Raiders. Few saw them and lived long enough to tell anyone. Slade made his way to Carry Farr’s Branding Pen Saloon and before the night was over, Farr had offered Slade a job as a lookout man from midnight to five in the morning. When an attempt was made on his life, the sheriff let him know that he considered Slade another owlhoot that needed watching. Looks like nothing is going to be easy, but he didn’t sign up for easy.
