Django is a gun runner who drags around a coffin that conceals a machine gun. He rescues a young woman, Maria, from being murdered by bandits led by Major Jackson.
After killing most of Jackson's men, Django makes a deal with a Mexican general, Hugo Rodriguez, who is in conflict with Jackson, and the two steal a large quantity of gold. When the General is slow in paying for his supplies, Django steals the gold. Unfortunately, the gold falls into quicksand. When Rodriguez catches up to the them, Maria is shot and Django's hands are crushed. Rodriguez and his men are massacred by Jackson, who then goes looking for Django in a cemetery.
However, Django, who has bitten the trigger-guard off his pistol, kills Jackson and his five surviving men.
