Yin Tianchou (played by Stephen Chow) has always been fascinated by drama and wants to become an actor. In addition to being a bit player, he also opens an actor training class in the neighborhood welfare association. At this time, the dancing lady Liu Piaopiao came here under the guidance of Mama Sang to learn how to act. It turned out that Liu Piaopiao had a very unpleasant experience. During Yin Tianchou's guidance, Liu Piaopiao gradually fell in love with Yin Tianchou, and she also became a popular lady in the nightclub. After Yin Tianchou received a lot of cold eyes, he finally got the appreciation of the big star Sister Juan (played by Karen Mok), who promoted him to play the male lead in the new play, but unexpectedly, his role was suddenly replaced, which disappointed him. The identity of the undercover police officer (played by Ng Man-tat) who was working on the set was exposed, and Yin Tianchou helped solve the case by mistake. After that, Yin Tianchou continued to be active in the actor training class of the neighborhood welfare association.
