(Synopsis): When the Yuan Dynasty rulers are threatened by the Mongol horde, the titular duo--a pair of lethal swordsmen--protect the imperiled imperial prince. It’s the Sung Dynasty versus the Chin invaders as the "Iron Triangle" of director Chang Cheh and stars David Chiang and Ti Lung truly hit their stride with this crowd-pleasing kung fu epic.
