Every spring in China, 130 million migrant workers exit the cities and travel back to their home villages for the New Year's holiday. This exodus is the world's largest human migration, a spectacle that demonstrates the world of a rapacious acculturating industrialism against the life of a rural past. Last Train Home follows the lives of one family who have embarked on the journey of hard labour and home again for almost two decades. One story of many of the human cost of China's ascendence as an economic superpower.
