Follows the story of underground workers who risked their lives to send intelligence and defend the motherland, set after Japan's attack on Pearl Harbor when the Wang Jingwei regime declared war on Britain and the U.S.

On December 7, 1941, Japan attacked Pearl Harbor. The following day, the Wang False Government followed Japan's declaration of war against Britain and the United States, and Japan symbolically occupied all of Shanghai. With the outbreak of the Pacific War, the situation of China's war effort changed completely. Members of the Chinese Communist Party underground risked sending out information to break the peace between Japan and Chiang and to defend the motherland.—themoviedb
