I saw a movie a few years ago around 2007 or 2008 but I never found out the name of it and it's been troubling me for quite sometime. I remember the movie being about a girl who invited her friends to a party out in the middle of nowhere and her friends found out that she invited them there to save them but they all ended up dying there. I also remember a girl with glasses who was late to the party and she had hit the girl while she was walking on the side of the road and didn't recognize her because she had shaved her head and was wearing a woodchhoodie. Then a big man came to help her and the put the girls body in a woodchipper and blood got all over the girl with glasses. That's all I remember.
