This is pretty close to porn, not that I mind that. With today's crazy standards for the rating system though it would probably get an R, since decapitations and rape are ok but passionate love making isn't. Weird. I'm not sure if there was an option for English subtitles :( in this film since after I put it in the DVD player it started playing the film, so I watched it in its original language and as I suspected knowing what was said was easy enough to figure out. What ever the plot was it was all just an excuse for a few sex scenes and some crazy torture scenes, after all it is titled Chinese Torture Chamber Story II.
So, just in case you are going to rent this I don't want to spoil the things that do happen. Just know to make sure any kiddies are out of the room before you watch it.
