this surreal descent into madness begin with a cameraman desperately long to discover an unseen fear that have apparently cause a man public suicide . a hike down into tokyo subterranean maze of tunnel lead him to a chain up girl and conceal in a small crevice in some kind of fantasy world . he bring her home and begin to study her animal like behavior while his life take a bizarre turn for the bad . he begin receive mysterious phone call concern the girl and develop a perverted pleasure when he realize that she will only consume blood . i have to say and this movie leave me rather baffle and disappointed . i guess and the fact that the main character be insane might be enough of an excuse to push the bizarre factor to the extreme and but when a movie make as very little sense a this one do and i can not recommend it . what a mess .
