Chiu Chi-Lung and Ng Kuai-Tak are two movie stunt actors in Hong Kong and are suspicious of Lung's father Chiu's mysterious behavior. Unbeknownst to them, Chiu was commissioned as a "messenger" by the Spirit World to take newly-departed souls to the other side. When Tak suffers a major accident on the movie set, Chiu keeps Tak's soul from being taken away, thereby, reviving him. Chiu is punished for messing with the Spirit World's procedures and Lung, unfortunately, becomes the next "messenger." Therefore, Tak looks to his father, who is a practicing Tao Priest, for help.
