Caring for an autistic adult can be seen as an act of faith. It is unpredictable. A regular interaction can lead to a violent lashing-out. However, due to its lack of exposition and its pure form of observation, the film captures something even more profound: life as a collection of failure, pain, and tragedy as felt by its protagonist, Chen Hung-tung, a father who cares with extraordinary patience for his autistic son Li-fu.
