Django Mata em Silêncio (1967)

Django arrives in the town of Santa Anna at the behest of a man named Sanders who'd been trying to buy safe passage for his cargo from a Mexican bandit named El Santo. Django finds that Sanders has been killed and that his rival, a man named Thompson, is now trying to deal with El Santo. Django, after a brief involvement with a beautiful young widow named Linda -- who has information on a lost gold mine -- becomes entangled in this situation by agreeing to escort a shipment through El Santo's territory.
