A photographer that does pictures of women in (shibari) rope bondage. The movie starts with the photographer rescuing a beautician who had been in the middle of a knife fight between two men. She becomes interested in him until she discovers his interest. Then she took becomes interested in it maybe.
From there the story meanders a bit. It is like they lost a random page or two from the script. A few scenes do not make much sense. Maybe the director did not care since everything was just to get to the sex and bondage scenes. This is a Roman porno film. Still, the better ones have a good script. I actually had to rewatch a few earlier scenes to see if I could make sense of it but it didn't help.
If you like to have a half decent story then you won't like this movie. If you only want to see the (simulated of course) sex and bondage then you might like it.
The cast was good but wasted. Even the story could have been excellent. It just lacked cohesion.
There are many much better Roman Porno films. Even some Dan Oniroku stories. Skip this one.
