King Chai (Roger Kwok) is the inept ruler of Qi, a state surrounded by larger neighbours and beset with hidden internal and overt external threats. The guardian spirits of Qi come to the aid of Qi and King Chai by arranging for Chung Mo Yim (Fala Chen) to become the Queen of Qi. Chung Mo Yim is skilled in magic, martial arts and the use of strategms, however she has been born with a prominent birth mark on her face and King Chai finds her ugly. The opponents of Qi in turn arrange for King Chai to become infatuated with Ha Ying Chun (Sharon Chan). King Chai takes both Chung Mo Yim and Ha Ying Chun as co-wives, with Chung Mo Yim becoming Queen of the West Palace and Ha Ying Chun becoming Queen of the East Palace.
