These Pinky Violence movies have always fascinated me. They are hard to find, I got my copies from Amazon Germany, so far I've watched 3 out of 4 of them and this is the one I like the most. First of all, this movie is violent and nudity recurs often, hella often! It is a dizzying combination of prison-movie archetypes, social satire, and S&M-fueled kink, that is definitely not for all tastes, but there's a surprising amount of artistry behind it. The story is very catchy and there is also torture in it. The movie itself is a pearl, like a picture of Japan in the 70's, I really recommend it because it has lots of stuff that will make you understand more about the culture and the way some Japanese conceive eroticism. The OST is even great! Lots of bass lines and percussions! If you love low budget movies, but violence, sex and torture and action, this movie is definitely for you! Lead actresses Miki Sugimoto and Reiko Ike are amazing! I read some reviews that defined the movie as disgusting and boring. I must confess it is not boring at all and the sex scenes are not explicit as in porn and there are still more violent movies nowadays even on TV. Give it a shot, if you are looking for some emotions!
