I hadn't heard of this film until recently. I read others commenting on the film's violence and brutality, so I was immediately interested. I can say that I was definitely surprised on how good this movie actually was, especially since it is a fairly unknown, lower budget production. The plot is pretty simple. An enslaved deaf and mute girl, called Angel, is given the role of "caretaker" to a house full of sex slaves, who are prostituted to the military. She befriends one of the girls there, which eventually leads to her revenge and escape from her "employers". I will admit, the first half or so of the film, can be a little slow. And the whole film is dark and bleak from start to finish. The last 30 minutes or so, the film picks up the pace. And when the film picks its moments to be brutal, it is just that, brutal. The special effects were great, which was a big surprise to me. The ending I thought was just so-so. I thought it was just a little too ironic how unlucky the main protagonist was, in that that she seems to running into 'bad' people that were somehow connected to the very same people she was trying to get away from. But even with that being said, I was still impressed with this one overall. The acting, production, and story (though simple) were all good. But the violence/special effects were really the strong point and the most effective part of the film to me. I recommend this one if you're interested in revenge-type of films. It's not on the same level of brutality or violence as a "I Spit on Your Grave", but it does pack a bit of a punch.
