Hannibal Heyes y Jed Kid Curry son dos de los delincuentes más populares y buscados del Oeste, especialistas en atracos a bancos y trenes, aunque siempre sin disparar a nadie. Se les ofrece una amnistía a condición de que se mantengan fuera de problemas durante un año y que no divulguen el trato. Es por eso que adoptan las identidades de Joshua Smith y Thadeus Jones, y emplean todo su ingenio para seguir fuera de la ley.
