Mason's first challenge brings him to Phnom Penh, the capital of Cambodia, where he will be getting to grips with a very different kind of cab - the tuk-tuk. Living and working with local driver, 46-year old Polo Doot, Mason takes his life in his hands as he learns to drive what is essentially a converted scooter on the chaotic streets of Phnom Penh. Through the eyes of his host, Mason discovers a country where inequality is surging, as the wealthy elite profit from a property boom, while a third of the population still lives on less than a few dollars a day. Mason faces an emotional and sometimes terrifying journey as he adapts to life in the Cambodian slums, where deep fried tarantula appears on the menu and where traffic mayhem is commonplace. By the end of his stay, the Cockney cabbie has to take paying customers as a fully fledged Cambodian tuk-tuk driver.
