Desperado

In August 1994 at the Tarasco bar in Mexico, an American man named Buscemi tells the story of how he witnessed a massacre in another bar committed by a Mexican with a guitar case full of guns. The bar's patrons are uninterested until Buscemi mentions the name "Bucho". Meanwhile, El Mariachi has a dream of his encounter with Moco, Bucho's underling, who killed his lover and shot his left hand, but Buscemi awakens him and tells him to continue searching for Bucho at the bar.
