Brimstone

"With his dying breath, an Indian Shaman unleashes an ancient curse upon his murderes, the miners of Brimstone, and the richest gold strike ever found in the High Sierras. A week later, the town's communication lines are cut. With all the honest men fighting the Civil War, the desperate mining investors put together a collection of outlaws and thieves to retake Brimstone. 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. In Brimstone, the most feared men in the West have finally found the very heart of fear itself."
