Instead of fighting over newly gained money from a coach-robbery, two gangster-brothers (El Bedoja and Chiuchi) decide to rob a bank together. But Martinez, a gangster-coward, is successfully questioned by Nigros (a clad-in-black gangster-killer who collects the money) and Rocco (a righteous ex-sheriff who doesn’t and shows off even more skill in using his pistol) on their plans. After having robbed the bank and needlessly shot several town-inhabitants, the gangsters hide out in a mine, taking beautiful Maruja with them as hostage. Although Rocco and Nigros follow different paths (Nigros the money, Rocco justice), they unite to get the money. They hire Esplotion for the explosives. Because Rocco is out of ammunition, he impales one of the gangsters with a wooden stake. A second showdown plays in a barn.
