Ninja Strike Force

The Ninja world is set ablaze when the mystical "Spirit Sword" is stolen by the Black Ninja Cal, giving its possessor the ultimate power of destruction. When the leaders of the five most powerful clans are murdered, a hunt begins to track down and retrieve the sword, leading to a titanic battle between all six clans as they demonstrate their ancient techniques. Richard Harrison stars as Ninja Master Gordon in this Hong Kong action film that combines elements from the 1981 Taiwanese Film "飛越補習班" with new ninja scenes.
