Brimstone 1-B

*With his dying breath, an Indian Shaman unleashes an ancient curse upon his murderers, the miners of Brimstone, and the richest gold stake ever found in the High Sierras. A week later, the town is overrun and its communication lines cut.

With all the honest men fighting the Civil War, the desperate mining investors put together a collection of outlaws, killers and thieves to re-take Brimstone ... by any means necessary. Led by 'The Viper,' a brooding gunslinger whose brutal exploits are the stuff of Western legend, the vicious posse finds the bullet-ridden town littered with dismembered corpses but its gold stores untouched. In Brimstone, the most feared men in the West have finally found the very heart of fear.
