Watch CineCalidad. A film producer, an assassin, and a patriot. These aren’t three characters in this film but three ways of describing Wu Dun, a member of the United Bamboo Gang who murdered the Taiwanese-American writer Henry Liu and became a producer of wuxia films. Hsu Che-yu, who previously brought Single Copy (IFFR 2020) and Re-rupture (IFFR 2018) to Rotterdam, visits Wu’s abandoned studio to restage the events with forensic scanning techniques.
