第二年（2011）春运，我们一如既往回到这个派出所……
除了那几位老“差人”，上一部片中的“新疆人”、“来广州混的少年”、“忏悔的青年”……没有一位再次出现。
派出所，普通人一生也难得进去一次，可也有人一个春运要进去好几次。故事就从一些总要在这进进出出的人说起……
影片似乎仍然是没有重点，结构松散，主题混沌。
其实，人本身就是一矛盾体，由人组成的社会注定也是如此。

DATONG follows the life and work of a controversial Chinese Communist Mayor GENG YANBO to tell the story about how he takes a radical reform to demolish 140,000 households and relocate half a million people to give way to restoration of Ancient relic walls in order to adopt a clean economic growth from tourism and culture, which he believes will do good to DA TONG citizen in the long term. With two years in the footsteps of GENG, along with the changing ideology and confrontations from the public, the film is trying to draw a looming shape of future of China.
