, China The documentary is narrated by Chai, who presents the results of her year-long research mostly in the form of a lecture, reminiscent of
Al Gore's
An Inconvenient Truth. The
Great Smog of 1952 in London served as historical evidence Chai in creating her film. She also speaks with officials from London and Los Angeles on how their respective cities have managed to deal with historic issues of pollution. She says she has a personal grudge against smog, and sets out to answer three questions: What is smog? Where does it come from? And what can we do about it? For the rest of this 104 min-long ‘Ted Talk-style’ film, she answers these questions, using animations, charts, interviews, historical clips, and site visits. Within the documentary, Chai features two child figures, one being her baby daughter in Beijing, and the other a six-year old in Shanxi, both victims of air pollution. She must keep her daughter inside "like a prisoner" on days where the air quality is particularly bad, which Chai's measurements indicated were about half of the days in 2014. In her interview with the six-year old, Chai asks, "Have you ever seen a real star?" The child responds, "No." “What about blue sky?” Chai asks. The girl says, “I’ve seen one that’s a little blue." “What about white clouds?” Chai asks. “No, I haven’t,” the child replies. She advocates cleaning up dirty energy in China to current US standards, by washing coal, using better quality oil, installing filters, and other clean-up technology. She advocates replacing coal, the dirtiest energy source, with natural gas and oil. The targets of her film include state-owned oil companies such as
China National Petroleum Corporation, which has also been the subject of the government's anti-corruption crackdown. These companies set their own production standards and the
Ministry of Environmental Protection is largely powerless to respond. Steel producers and coal plants also ignore regulations to maximize profits. ==Release and ban==
