A vivid portrait of a generation of Hong Kongers committed to creating a new more democratic Hong Kong. Schoolboy Joshua Wong dedicates himself to stopping the introduction of National Education. Whilst former classmate Ma Jai fights against political oppression on the streets and in the courts. Catapulting the viewer on to the streets of Hong Kong and into the heart of the action. The viewer is confronted with Hong Kong's oppressive heat, stifling humidity and air thick with dissent. Filmed over 18 months this is a kaleidoscopic, visceral experience of their epic struggle.
