"Investigating My Father" is a film made by a son to investigate his father's history. It documents the process of the son's investigation over twenty years into his father's history before 1949, which he had kept from his son. The father was a landowner's son and an ex-Kuomintang Air Force pilot, who remained in mainland China after 1949. In order to survive, he tried to transform himself from a man of the "old society" to a man of the "new society." "Investigating My Father" is however not a film just about a father. Since the filmmaker is the subject's son, the film also inevitably tells a story that unfolds between a father and a son.
