As pro-democracy activists and armed police battle in the streets of Hong Kong, ordinary citizens are choosing sides. Historically an outlier of both western and Chinese power, Hong Kong wields its own economic force, affording the city and its people a spirit of independence that has now erupted into clouds of tear gas. Filmmaker Bing Zhou uses a nimble camera to follow a group of protagonists—two opposing political candidates, a tea shop owner, a cab driver, a police officer, a paramedic—on two separate days of conflict. On September 21, 2019, protestors from three districts join forces, resulting in unprecedented violence. Just 10 days later on October 1, the National Day of the People’s Republic of China, previously undecided onlookers show their stripes. Thoughts transform into action in this demonstration of how mercurial and personal Hong Kong’s politics have become.
