Texas Ranger Lieutenant Jim Blawcyzk is on his way to the easiest assignment he's had in a long time... until a fellow Ranger, a man Jim trusted as a friend and partner, murders their commanding officer and puts two bullets into Jim. Now, with Jim lying gravely wounded in a hospital bed, his long-time partner Smoky McCue, along with Jim's son Charlie, newly appointed to the Rangers, must try and track down the Ranger turned killer. The only problem is the renegade lawman has powerful friends and allies in Mexico, and they are determined to keep him safe from Texas law, at any cost.
