Description：Ou Mijia (Eric Ng) is a clerk with a mild personality. He is often pranked by others and has become accustomed to it. Ou Mijia has a crush on the female nurse Dkny (Athena Chu), but is unable to get close to her. Ou Mijia accidentally discovers the affair between the company's prince and is tricked by the trickster invited by him. He even loses his job and has to join the "super trickster king" Holland (Natalis Chan). Since then, he has learned tricks from his fellow apprentice Wu Guangde (Alex Lui) and others. Soon, Columbus (Lucy Lui), the son of Hong Kong tycoon Mr. Ko, invites Holland and his friends to trick Xiao Xiao in order to expel his father's illegitimate daughter, Xiao Xiao, who was left in France. Unexpectedly, Wu Guangde has a special liking for Xiao Xiao. In addition, Mr. Ko's personal nurse is Dkny, so Ou Mijia and others have no intention of playing tricks on Xiao Xiao. Columbus is furious and invites the trickster to clean up the mess.
