This, I am ashamed to say, was my first exposure to the wonderful world of Cat III Hong Kong cinema. I sat there for the whole movie saying "wow, I didn't know Joe D'Amato had moved to Hong Kong."

The movie opens with the seemingly mentally slow Ah Kai (Cat III fixture Anthony Wong, last seen on these shores in Black Mask) having, erm, relations with the boss' wife. When the boss walks in on them, hilarity ensues. Kai ends up slaughtering the family, with the exception of the daughter (once again, he gets walked in on), and fleeing to South Africa. (Not a spoiler. We're five minutes into the movie.)

Kai has become a waiter in a popular Chinese restaurant in South Africa. If anything, he's gotten slower. His misanthropic tendencies have been honed to razor-sharpness by the treatment he receives from the boss (kung-fu flick veteran Meng Lo, recently in the third installment of Sex and Zen) and his wife. One day, while off buying meat in zulu country, through a series of events best left to the reader's imagination, Kai contracts ebola. He is, however, one of those rare people who will survive the disease and become a carrier...

Everything about this movie can be summed up in the word "nasty," the same way it can with Joe D'Amato joints. Yau (The Untold Story), however, keeps things on the up side of D'Amato with a grisly sense of humor that pops up just when it's needed. As with most exploitation flicks of this sort, the plot is bone-thin and often transparent, the acting is average at best, and the camerawork is nothing special. It's a fun little movie if you have a really strong stomach, but not something you could hold up as a shining example of the genre... I hope. ***
