Nowadays, most people know who Jackie Chan is. But just who Jackie Chan really is, was something that this Hong Hong and Hollywood star didn't even know himself until just recently. In 1999, Jackie Chan's mother's health began to fail and his father decided to tell his son the whole family story: Jackie Chan have brothers and sisters in the People's Republic and, his surname was not Chan at all originally. Jackie Chan's father worked in Chiang Kai-shek's regime as a spy for the Nationalist Party and his mother was anything but a simple housemaid. This film follows the traces of this family, whose fate is far from unique in China. Again and again, families were torn apart by the turmoil of the Second World War, the Civil War, and, later, the Cultural Revolution.
