During an audience with the Emperor, Lingling Fats seemingly useless inventions and his ignorance of martial arts enrage the Emperor, who demotes him to menial tasks around the palace.Meanwhile, Faceless, King of Kam Tribe, plans to assassinate the Emperor and overtake China. The Kam Tribe creates a diversion by inviting all the doctors of China to a medical exposition in which an alien is to be dissected. Ling Ling Fat and the Emperor separately depart for the event. While Lingling Fat and his wife feast at a string of restaurants, Kams men kill the Emperors three remaining bodyguards. The assassins put the unconscious Emperor in an alien costume to present him as the alien for dissection. Just as Lingling Fat and the other doctors discover the Emperors identity, Kams assassins begin to slaughter everyone in attendance. Lingling Fat uses his wits and inventions to defeat the assassins. ........
