One of the many, many films with bak/pai mei, aka white eyebrows: the story was a little lost in translation i think on this one, but it's a good chapter in the white eyebrows saga.
A history lesson for those who don't know White Eyebrows: Back in the day, the original southern Shaolin Temple, (Xiolin if you want to be authentic [x is pronounce sh in chinese]), anyway, the southern Shaolin temple worked for the government to help out in fighting Xilu warriors. After the monks were able to defeat the entire army with relative ease, the government became concerned they were too powerful, and decided to kill them all. They burned down the temple and hunted down the survivors until only 5 elders remained. 1 of those 5 was White Eyebrows. Some say he was going to be sent in as a spy to help the 5 avenge their fallen brothers, by way of internal sabotage. Some say he was bought off by the government and turned on his fellow monks. Some say he just realized fighting the government was useless and would only result in death, and so deserted the other monks... whatever the reason, he has become arguably the most infamous villain in chinese folklore, and is featured in over half of the old kung fu movies as the star bad-guy. He is almost invincible and more or less unkillable. Some say he never really existed, while others say the fact that there are both white lotus and bak mei styles of kung fu, shows that it is entirely possible he was in fact real.
