China is under attack. General Huang Lung has been defeated, his army destroyed by the invading Mongol forces. Kao Chiu acts swiftly to appease the Emperor, recalling General Hu from political exile to lead China's forces against the invaders. With a string of successful campaigns the General soon beats back the Mongols; Kao is credited with choosing General Hu to lead such a vital campaign. Wary of General Hu, Kao hatches a further scheme, which sends the son of the General, Hu Yen-I, on a suicide mission against Liang Shan Po, hoping that this will spur General Hu into action. If one man can defeat Lin Chung it is his former commanding officer, General Hu.
