Some time during the 1930s amidst the
Second Sino-Japanese War, Chinese secret agent Fok Ming-ming is sent to Kaa Yi near Tibet to investigate the Japanese occupation that has been set up there. Ming-ming meets with Secret Agent 001, another Chinese secret agent who is to be her contact in Kaa Yi. They first run into a conman and then a rebellious princess, Chin-chin, who join them on their adventures. Ming-ming and her friends discover that the Japanese occupation plans to convert the town into a weapons manufacturing site, but they are captured before they can warn the locals. Before the group are to be executed (along with Youda, Chin-chin's lover and a local aristocrat who stands up to the Japanese despite initially colluding with them), the locals chant for their release and the local Kaa Yi army turns on the Japanese, firing at the Japanese command and freeing Ming-ming and her friends. The once peaceful citizens of Kaa Yi then prepare to defend their town against the Imperial Japanese Army, under the guidance of Ming-ming and her friends. ==Cast==
