Two "blokes" go hiking and get slaughtered. At the same time a butterface and her chubby cousin also go hiking. The butterface has so many piercings in her face that fear registers as smiling and her screams sound like a horse-laugh. Oh, and butterface wears a tiny skirt with no underwear and untied Doc Martins because...hiking.
This movie is summed up in one scene: chubby cousin is taking a dump in the woods and asks butterface to find something to wipe with and...SURPRISE!...we get the exposition from a fragment of newspaper that just happens to be lying on the ground. Seriously. After she's done, one of the (I hate to call them psychos because they just kind of grunt and screech) eats the feces. They pay such little attention to detail that when the feces-eater picks up the clipping it remains unstained.
There's several "bathroom scenes" and lots of torture including an apple gag secured through the *sides* with...chain. Yay physics! Note to torture porn makers - if you're going to tie someone done don't film the obvious slack in the ropes/chains. It just looks sloppy.
There's not much atmosphere or mood beyond screaming "I'M TELLING YOU THERE'S SOMEONE OUT THERE", the stupid shrieking of the torturers and, of course, no cell phone reception. Again, when the lead woman looks and sounds like she's laughing when she should be terrified...that's a problem.
Effectively, the disgust you'll feel is with the filmmaker, not the content.
