The Cisco Kid and Poncho are about to be executed by the French, who have taken over part of Mexico, when an attack on the prison by rebels allows them both to escape. Still chained together, they steal a burro and ride to a nearby village where they come upon a tax collector and several soldiers in the process of taking money from the villagers. The pair manage to overcome the soldiers, and using their guns, free themselves from the chains and rob the tax collector.
