On His Majestyâ€™s Secret Service
For generations, the Secret Royal Guards has been protecting the emperor. The 12 agents are named after the 12 Chinese Zodiac Animals and are assigned different duties. Among the current
group, Agent 00Tiger is the best in martial arts while Agent 00Dog (Louis Koo) is considered the weakest as a bodyguard. His forte is in inventing strange impractical devices rather than practical kung fu. The Emperor and Empress (Sandra Ng) are selecting a suitor for their Princess while the Chief eunuch, Unicorn, is plotting to kill the emperor. Uncovering Unicorn's evil plot, agent 00Dog decides to eliminate the enemy in his own way.
