Filmed over 18 months, Lessons in Dissent is a kaleidoscopic portrait of a new generation of Hong Kong democracy activists. 18-year-old Joshua Wong dedicates himself to stopping the introduction of National Education. His campaign begins to snowball when an interview goes viral on social media. With the new school year fast approaching, a showdown with the government seems inevitable. So with a microphone in hand, and still in his school uniform, he takes to the streets to protest, along with 120,000 people in support. Meanwhile, former classmate Ma Jai fights against political oppression on the streets and in the courts. Having dropped out of school and dedicated himself to the movement, he endures the persecution suffered by those not lucky enough to be protected by the glare of the media. Lessons in Dissent catapults the viewer on to the streets of Hong Kong, confronting the viewer with the country’s rising energy of dissent.
