In the winter of 1942, two months after the French Concession in Shanghai was taken over by the Japanese army, Shen Yanzhi, the general manager of Yuchang Matheson Company, had just wiped off the "traitor" graffiti on the door wall - a humiliating normal condition for pseudo-officers. At the critical moment, he rushed into the wine car to block the bullet and save Asano, but his brother Shen Yanming publicly denounced him as "collaborating with the enemy" and covered him up with harsh names.
Crisis ensues: Asano uses his mother's house arrest license to force interrogation (a common method used by the Japanese military to control family members). The military commander mistakenly believes that he has surrendered to the enemy and secretly assassinates him. The underground organization his younger brother contacted turns out to be a mole! Shen Yanzhi, who is surrounded by enemies on three sides, is actually carrying a top-secret mission - to intercept the second phase of the Japanese army's "Qingxiang" plan recorded in the "Wang Puppet Qingxiang Files" and blow up the German-Japanese incendiary bomb arsenal.
In order to break the deadlock, he teamed up with his classmates Asano, who was hostile to the CCP, and Lu Chengan, who was hostile to the CCP, to form a ridiculous but deadly team: a "Declaration" reporter who hid explosives in his pen, and a doctor in Germany who could crack the Enigma code. Information was spread through verbal exchanges at a banquet, a foreign company set fire to destroy perjury within seven minutes, and the mother outside the cell knocked over the medicine bowl to restrain the guards...
Shen Yanzhi uses resourcefulness as a blade and faith as a shield. In the shadow of swords and swords in the ten-mile foreign battlefield, from "fighting alone in a boat" when dealing with the Japanese, puppets, and military commanders alone, to joining hands with comrades with completely different positions to "break the situation with a sharp knife", he performs a passionate faith drama of "I would rather die than be a slave to the country's subjugation"!
