A career criminal known only as Driver crashes through the U.S.-Mexico border while being chased by the authorities. With a bleeding bullet wound and $2 million in stolen cash, he struggles to elude capture but is ultimately apprehended by Mexican law enforcement. Instead of being turned over to the U.S. police, he is sent to El Pueblito, a notoriously rough and complex Mexican prison where inmates run the show. There, he quickly learns that survival requires navigating through a web of corruption and violence; a reality starkly different from any American penal system. Despite being a foreigner in a hostile environment, Driver's gritty resilience allows him to adapt, as he begins to understand the unique economy and social hierarchies that dictate life within the prison walls.

Inside El Pueblito, Driver encounters a 10-year-old boy with a liver issue who has an invaluable knack for navigating through prison life, as the kid is both resourceful and knowledgeable about the internal workings of this criminal society. The boy's mother is also incarcerated, and it becomes apparent that their lives are dangerously intertwined with that of the prison's kingpin, who harbors sinister plans for the boy. Forming an unconventional bond, Driver takes it upon himself to ensure the safety of the child, employing his criminal expertise and cunning to outmaneuver enemies. As he delves deeper into the corruption at the heart of El Pueblito, Driver finds that his quest for survival evolves into a fight for justice, redemption, and a chance at a clean slate.
