During the Second World War, the son of a Grenoble collaborator went up to his grandmother’s house on the Vercors plateau to wait for the war to end without him. On July 21, 1944, German troops overran the plateau. Forced to flee, he joins a small group of Resistance fighters and civilians, and struggles to survive for three days and nights.

Once the thriving capital of Imperial China, the city of Datong now lies in near ruins. Not only is it the most polluted city in the country, it is also crippled by decrepit infrastructure and even shakier economic prospects. But Mayor Geng Tanbo plans to change all that, announcing a bold, new plan to return Datong to its former glory, the cultural haven it was some 1,600 years ago. Such declarations, however, come at a devastatingly high cost. Thousands of homes are to be bulldozed, and a half-million of its residents (30 percent of Datong’s total population) will be relocated under his watch. Whether he succeeds depends entirely on his ability to calm swarms of furious workers and an increasingly perturbed ruling elite. The Chinese Mayor captures, with remarkable access, a man and, by extension, a country leaping frantically into an increasingly unstable future.

The film is set in five parts, five seasons that are part of the Chinese almanac. The story takes place in the jianghu, the world of the martial arts. Ouyang Feng has lived in the western desert for some years. He left his home in White Camel Mountain when the woman he loved chose to marry his elder brother rather than him. Instead of seeking glory, he ends up as an agent. When people come to him with a wish to eliminate someone who has wronged them, he puts them in touch with a swordsman who can do the job.
