Changhua Zhang and Suqin Chen are a couple from a rural village in China's Sichuan province. Frustrated with their lack of employment opportunities, they traveled to the industrial city of Guangdong and took jobs with a large textile firm, making clothing for export. However, Changhua and Suqin were not able to bring their two children with them, and since then the kids have been raised by their grandparents, with their mother and father staying in touch though occasional telephone calls. The only time they have a chance to see their now-teenage children is during China's annual New Year's celebration; they are among the 130 million Chinese whose work keeps them away from their families and make the trip home during the holiday, resulting in an overcrowded rail system as the trains struggle to keep up with the rush. Filmmaker Lixin Fan follows Changhua and Suqin over the course of several years in the documentary Last Train Home, as the couple makes the long journey home (over a thousand miles) only to find that their family is slowly falling apart -- 16-year-old Qin and her younger brother, Yang, are all but strangers now to their parents, and the youngsters have come to resent their parents, while Qin considers leaving school to move to the city on her own and get a job. Last Train Home received its world premiere at the 2010 Sundance Film Festival.
