A band of ruthless and deformed marauders led by the horribly blind Jack Thunder, attacks the villages of the West, massacring, raiding and then setting fire to everything! The plague is about to hit Heaven, a thriving and peaceful mining town where Lena and her daughter Donna live, great friends of the pards, emotionally linked to Carson and Kit Willer! The rangers, after stopping in Heaven, head for Dogtown to catch Jim Lean, a gambler who killed a sheriff, and his brother Bronco. Meanwhile, Kid Rodelo, Jack Thunder's young assistant, shows up at Lena and Donna's inn... Tricked away from Dogtown, the rangers can't defend the town from Jack Thunder's "pack"! The infernal bandits, who are looking for the gold of the Band of the Innocents, carry out an extermination and burn everything and then head for Heaven, where Lena and Donna live. The pards fall flat on their faces in the direction of Heaven, getting stuck in an incendiary trap. Meanwhile, the seven assassins have arrived at their destination and, as a first move, they change the name of the peaceful town, renaming it Helltown! The young outlaw Bronco Lane, to avenge his brother killed by Thunder's gang, helps the pards reach Heaven, where the assassins hope to get information about the Band of the Innocents' gold from Lena and Donna! Using Kid Rodelo, a clean-faced killer, as a fifth column, the bandits lay waste to the peaceful town. But the loot no longer exists: Lena invested it some time ago in her inn. One by one, the marauding psychopaths are eliminated, and Jack Thunder, hunted by Tex, ends up buried by a landslide in an abandoned mine!
