The film depicts the Chinese Expeditionary Force fighting in Burma. In 1941, Japan's conspiracy to sweep through Southeast Asia was clearly exposed, and the Yunnan-Burma Highway, China's only link to the outside world, was in jeopardy! Chiang Kai-shek urgently summoned Duan Zhongyi (Zhang Fengyi), a lieutenant general of the Yunnan army, and put him in charge of military coordination with the Allied command. Duan Zhongyi took an active part in the planning of the Burmese War, and his sons and daughters went to the battlefield of resistance against Japan to fight bloody battles, and died nine times to expel the Japanese from the country, composing a magnificent chapter in which the heroic sons and daughters of China fought against foreign insults and sacrificed their lives for the country.
