Desperado

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 El Mariachi, Bucho's underling, who killed his lover dead and shot his left hand. He is awakened by Buscemi, who tells him to continue his search for Bucho at the bar.
