In the 1930s, before the Western powers entered World War II, a Japanese death cult called the Temple of Hades is ordered to work alongside the military to aid in the spiritual destruction of China. The elite warriors believe that the war can be won without the use of man-made weapons. Many years later, one of the children is now the greatest assassin in the temple, and he escapes to China and joins a Shaolin Temple, where he vows to protect his own country against the Japanese.
