Liang Jiaxiang, who appears to be the owner of a Siyi trading house that handles the overseas Chinese batch business, is actually a core member of the "Chaoyang Group" of the Communist International's Far East Intelligence Network. Assigned by the South China Branch, he returned to Hong Kong to track down a mysterious missing donation of 50,000 silver dollars from overseas Chinese. He was shocked to hear that his contact "Lao Zhou" died tragically on the streets of Wan Chai, and his partner "Red Cotton" was also assassinated in Guangzhou.
As the investigation deepened, Liang Jiaxiang discovered that this amount of money affected the nerves of many parties: the Japanese "Sakura Agency" agents, the Guangzhou Station of Military Tong, the Hong Kong Station of Central Unification, and even the "Siyitang" overseas Chinese batch network controlled by his father were all involved. During the investigation, he had entanglements with three women of different identities:
Lan Huan, the daughter of a wealthy Nanyang businessman, looks arrogant and willful, but is actually a member of the overseas Chinese guerrillas in the Philippines;
Natsuko, a top student at Waseda University in Japan, has a tattoo of the Naval Intelligence Service hidden under her elegant and intellectual appearance;
Nancy Wilson, a US OSS agent, approached Leung Ka-cheung as a reporter.
From the dark alleys of Hong Kong to the docks of Penang, from overseas Chinese batching secret letters to sugar smuggling, Liang Jiaxiang gradually uncovered a shocking conspiracy - the Japanese army was using overseas Chinese merchant ships to smuggle strategic materials, and a traitor code-named "CX-7" lurked within the organization. When the artillery fire from the fall of Guangzhou illuminates the Pearl River, he must make a choice between love and faith, family and ideals...
