Standing before Pancho Villa's tomb, horse breeder Jesus harkens back to his youth, when he provided bed and board to a nondescript laborer named Doroteo Arango. In time, Arango would transform himself into gang leader Villa. When the Mexican Civil War erupts, a man named Fierro wants to execute Jesus for selling a horse to an anti-Villa buyer. But in repayment of Jesus's debt of kindness, Villa intercedes on his behalf.
