Despite the title, this is actually not a documentary. Paul Naschy plays a seedy handyman hired on by three eccentric sisters. Shortly afterward, blond-haired blue-eyed women start turning up dead. According to several reviews, the copy I found is completely bereft of nudity. It's the World's Worst Videos (VidAmerica) brand, which I've never seen, so I'm not really sure. This is some Matt Clark shit.
No thanks goes to the douchebag who disabled embedding. All the credit goes to North Korean ex-pat Donlee Brussel for making use of this trailer possible.
