She is not aware that he is actually on an undercover mission to take down Lupercio, a guerrilla leader, for murdering the wife of a noted drug lord. Meanwhile, Lupercio is caught up in a disagreement with Ernestico, the leader of a Revolution, over political viewpoints. This disgreement will result in the ambush of the bus carrying Ismael, bringing Lupercio face to face with the man hired to kill him.
