In a nutshell: A man is introduced to a whorehouse where he meets a gypsy woman who introduces him to a sexual object that she calls 'The Special'.
This is a low budget movie and it shows. It's like a long episode of one of those classic horror tv-shows. Because of the sexual nature and twisted dual sided ending, it probably wasn't made an episode for one of those series. That leaves movies, so it had to be stretched. It has been written before: The movie could/should have been shorter. Acting really isn't that bad, neither is the script nor screenplay or pace. The overall picture is average but professional, at 3/4 of the movie you start to guess where it is going.
This movie is however a must see because of the twisted plot and how that turns out, and not just for die hard horror fans.
