Jiang He (Tsuruda Matsushita) was adopted by the Japanese military officer Tsuruda Igawa since he was a child. He claimed to be a child born in the inner chamber. After years of underground professional training, he went to Hong Kong to assist the military officer Yoshida Masaichi in controlling governance and eliminating underground party members. The first task was to obtain the highest financial support. Japanese executives unanimously decided to start with Lu Chuan, the returnee son of Hong Kong's largest capitalist, to test Jiang He's loyalty and send him to complete the task.
