As the Western U.S. becomes more settled, and new communities are forged from the wilderness, an age-old battle intensifies. Wildfires that used to burn through remote and desolate areas now threaten to claim lives and buildings, and more and more of these deadly fires are caused by human carelessness. Join the elite group of firefighters known as the "Hotshots" who risk their lives to control the annual fires that blaze across the West. Follow them through the rigorous training process and learn of the extraordinary measures they employ to fight the flames that erupt far beyond the reach of conventional firefighters. Amazing footage from some of the worst forest fires in history shows the Hotshots in action, as smokejumpers, tanker pilots and support crews risk their lives in the face of the inferno. It's a blistering journey into hell on earth.
