In 1933, 20,000 Japanese soldiers and 50 tanks invaded the Pa Tou Lou Tzu, a strategic key point of the Great Wall. With only seven men stationing, these heroes took on the entire army for five days before succumbing. Director Chang Cheh recreated this epic battle with his favorite cast including Ti Lung, David Chiang, Alexander Fu Sheng and Chen Kuan-tai, as a celluloid tribute to these nameless souls.
