El Mariachi volgt het spoor van drugsbaas Barrillo door het woeste landschap van Mexico. Barrillo is van plan een coup te plegen tegen de Mexicaanse president. El Mariachi is ingehuurd door de corrupte CIA-agent Sands, die uit is op vergelding tegen zijn grootste vijand.
Nee, helaas is Once Upon a Time in Mexico nog niet beschikbaar op Netflix in Nederland.
