While on the lam in Mexico, Irish Republican Army demolition expert John Malloy (James Coburn) hooks up with Juan Miranda (Rod Steiger), a crass, stogie-chomping bandit with designs on the Mesa Verde Bank. Reluctant partners with differing agendas, they find themselves caught up in the turmoil of the Mexican revolution when their heist nets more than gold in director Sergio Leone's sprawling 1971 Western.
