In a stock teen drama with a twist, the adult hero is Hoi Sunkuai (Raymond Wong) a teacher at an all-girls school -- and an incarnation of the "Happy Ghost" Zhu Ganzhun who has supernatural powers. Hoi's problems start when a trio of student tricksters are out to do him wrong, just for the fun of it. After a miscalculated use of his special powers, he is called on the carpet in the headmistress's office -- and is immediately smitten with her. But his future is set when other mishaps get him fired. Now his only hope of reinstatement lies in the trio of culprits that got him into trouble in the first place.
