Once Upon a Time in Mexico

El Mariachi is recruited by CIA officer Sheldon Jeffrey Sands to kill General Emiliano Marquez, a corrupt Mexican Army officer who has been hired by Mexican drug lord Armando Barillo to assassinate the President of Mexico and overthrow the government during a period of unrest in Culiacán (the capital of Sinaloa) which is testing the presidency. Many years before, El Mariachi and his wife Carolina confronted Marquez in a shootout and wounded the general; in retaliation, Marquez took the lives of Carolina and their daughter in an ambush. In addition to El Mariachi, Sands persuades former FBI agent Jorge Ramírez to come out of retirement and kill Barillo, who had murdered his partner Archuleta in the past. Furthermore, AFN operative Ajedrez is assigned by Sands to tail Barillo.
