To be made welcome at the town called Hell in the Palo Duro, a man had to have a price on his head and be willing to share his loot with the mayor. If he did, he would be safe from the law. By arrangement with their chief, the Kweharehnuh Comanches protected Hell and kept away unwanted visitors.
Being determined to wipe out the outlaws' stronghold, but wishing to avoid starting an Indian war, the Governor of Texas asked a friend for help. So Ole Devil Hardin's floating outfit set off on another dangerous assignment. Not only did Dusty Fog, the Ysabel Kid and Waco have to get by the Kweharehnuh, they had to try to stay alive once they reached the town called Hell.
