The story begins as archaeologists discover a crudely made artifact while doing an archaeological study before the entire area was to be flooded following the construction of the Three Gorges Dam.

The archaeologists identify it as being made by Mak-zi (also known as "McFat"), an ancient Chinese philosopher who had invented many things, but were arguably ahead of its time - for example, a myriad of electronic devices before the discovery of electricity.

Due to mounting debts from failed ventures and economic hardships, McDull's mother, Mrs. Mak (Sandra Ng), decides to leave their home in Tai Kok Tsui to find fortune in the mainland.

He then turned his attentions to opening the Spring Flowers Gate, taking on the guise of Brother Panda to get new recruits and to comfort students at the academy.

While at the competition, McDull notices his friend from Hong Kong, May, who had enrolled in a "wire-fu" summer camp sponsored by Yuen Woo-Ping, also competing in the contest.

Taking a break from her mundane life, she traces the clock to its location, and find a quaint restaurant in the middle of Hong Kong's concrete jungle, run by the adult McDull.
