Looking for an instant-disaster formula? Try a wagonload of murderous convicts, escorted by a Cavalry officer and a handful of guards. Then add the officer's two beautiful young daughters, who inexplicably go along for the ride. You're way ahead of us: there's an accident, the guards are killed, and the nine convicts run riot. This gruesome spaghetti western looks more like a "splatter" film, with no one spared the gore.
