This is the story of Thomas McFadden, a small-time English drug smuggler who was arrested in Bolivia and thrown inside the notorious San Pedro prison. He found himself in a bizarre world, the prison reflecting all that is wrong with South American society. Prisoners have to pay an entrance fee and buy their own cells (the alternative is to sleep outside and die of exposure), prisoners' wives and children often live inside too, high-quality cocaine is manufactured and sold from the prison, and all the police from the governor downwards can be bribed. Under the surface is a frightening level of violence - Thomas's life was often in danger and one of his friends was murdered by the police when he threatened to expose the corruption in the prison.
