El Presidente is obviously the President of Mexico.
He is one interested in helping the people to his greatest extent. Unfortunately, the Barillo cartel has other ideas, and they include assassinating him.
El Presidente's Advisor is also in on this assassination plan.
El Presidente escapes by switching clothes with El Mariachi and walking out with Lorenzo and Fideo dressed like a civilian.
He escapes without injury and rewards the mariachis for their help.
