Underground Knight

During the Anti-Japanese War, in Xinjing, the capital of the puppet Manchukuo State, young national high school students Ou Tong, Shen Mengxi, and Xi Xicen devoted themselves to the anti-Japanese movement. Under the leadership of the Kuomintang and the Communist Party, they destroyed the reactionary film "Today's Manchuria" produced by Manchuria to promote the harmony between Japan and Manchukuo, and successfully prevented the film from entering the League of Nations to deceive the world.
