Lucy Ash investigates the greatest movement of people in human history: the 100 million Chinese who have moved from the country to the booming cities over the last 15 years. She meets a self-taught lawyer who fights for the rights of migrant workers mutilated by industrial injuries. His clients often wait years to claim compensation from ruthless sweatshop owners who know how to bend the rules. And she visits a remarkable school for the children of migrant workers, who face discrimination in the public school system.
