2. The play tells the story of a series of life-and-death battles waged by the puppet agents of China, the Communist Party of China (CPC), Japan and the French Concession for a secret document "The Secret Treaty between Japan and the King" during the War of Resistance against Japanese Aggression period.
3. At the end of1939, after the Changsha Battle, War of Resistance against Japanese Aggression entered the stalemate stage. At the same time, Wang Jingwei stepped up the establishment of a pseudo-national government in Shanghai, which made the anti-rape actions of the military system in Shanghai more frequent. At this time, a special person came to Shanghai from Japan. He was Qin Wenlian, an important minister in Wang Jingwei's cabinet. Qin Wenlian came to Shanghai and completed the signing of a secret traitorous agreement between Wang Jingwei and Japan, which enabled Wang Jingwei's puppet government to be successfully established.
4. Feng Ru Tai and his gang assassinated Qin Wenlian. At the same time, Jiang Hong, an underground party of the Communist Party of China, also received an order from Yan 'an to obtain an important information from Qin Wenlian-the content of the traitorous agreement signed by Wang Jingwei and the Japanese. This is a top secret traitorous document. Only by making this document public can we thoroughly expose Wang Jingwei's traitorous behavior and expose the Japanese king's peace lies. For a top secret document, "The Secret Agreement between Japan and the King", agents from China, the Communist Party, Japan and the Puppet countries launched a series of life-and-death contests. Finally, the "Japan-King Agreement" was published in Hong Kong newspapers, and Wang Jingwei's traitorous behavior was revealed to the world.
