The play tells the story of the secret service group "No.5" arriving in Shanghai all the way, living in the French Concession, and all of them are "upper class" in public. In the contest with the Special School of Japanese Gendarmerie Command and the "No.76" of Wang Puppet Agency, especially with the head of the Special School of Kenji Junyuan High School, Miko Sakai, they took risks repeatedly, but finally completed the task.
The story happened on August 3rd 1937. After the July 7th Incident broke out, on the eve of the August 65438+03 Incident in Shanghai, the Japanese secret service in China issued a secret order to assassinate Chiang Kai-shek. Japanese spies were rampant at that time. Therefore, Ouyang Jianping, a lieutenant colonel of the Ministry of National Defense of the National Government and a member of the underground party of the Communist Party of China, convened five young people with unique skills according to the instructions of Mr. Feng, the leader of the underground party organization, and secretly formed the "No.5" agent group.
