Tsui Hark and Ching Siu-ting spin this adventure yarn inspired by old Hollywood adventure serials. Set in the 1930s when China's last emperor Puyi allies himself with the invading Japanese army, the film centers on aged though wily Dr. Choy (Dean Shek) vows to lend his experience and his medical expertise to the resistance. He teams up with the luckless Lieutenant Mang (Paul Chu Kong) whose ragtag army needs all the help it can get. After a hair-raising encounter with spy WO-1 (Fennie Yuen), the force decide to take out a chemical weapons factory located deep in Japanese held Manchuria and run by the evil Masa (Tony Leung Kar-fai) and legendary secret agent Yoshiko Kawashima (Joyce Godenzi). Corey Yuen and Jacky Cheung also star.
