Paraphrase on the famous Chris Marker's film from 1956 "Sunday in Peking". The actual life of the Chinese town that is experiencing the fastest evolution, and has thus became the symbol of modern Chinese economics. On two sides of one river are two symbolic towns. Red flags, monumental sculptures, realistic communist architecture of the fifties are all symbols of the successful communist revolution. A ferry links this town to the other, a town of skyscrapers, a town of the future, the modern district of Pudong being the new Chinese symbol: economy above all.

The film describes, using Shanghai as an example, the paradox and problems of modern China: population politic, traditions and the acceptance of western civilization, the amalgam of communism and capitalism.
