The Nueces Strip in southwest Texas of 1875, harbored Mexican border raiders, Texan vigilantes, a mixed population of cattle ranchers and hard scrabble farmers, all fighting the land, the weather and each other. Into the cauldron descend 40 Texas Rangers, under the leadership of Captain Leander McNelly, with orders to stop the raids, quell the fighting and bring peace to the strip. Based on historical events, the tale takes us into the lives of Rangers, raiders, ranchers and farmers as they endure the hardships of this violent chapter in Texas history.
