The Buddhism Palm Strikes Back

The legendary Buddha's Palm is the most powerful skill in the kong-woo (martial artists' community) that any fighter can learn. A long time ago, Lung Kim Fei used the skill to defeat Tin Cam Kiuk and has since retired from the kong-woo. Lung laid down a family rule, forbidding his descendants from learning the skill, and hid the Buddha's Palm manual, in order to prevent them from misusing it.
70 years later, a mysterious red-haired martial artist known as "For Wun Tse San" (literally: Fire Cloud Evil Deity) appears and goes on a rampage to kill several people before challenging the five major sects to a fight. The five sects misbelieve that Lung Kim Sang, a descendant of Lung Kim Fei, is responsible for the killings and attack him.
