I never saw the beginning part. A group of young people are there. They came for some camping I believe.one after another gets brutally murdered by someone.they suspects each other as murder. There is a weapon like an electric saw

Again I want the name of another movie. It has a word America or American .its not from American pie series. Its something else. The movie is filmed after 1990.
Actually my friend asked this question.
Note: she said there is two words in the film name .maybe twin( I am not sure if this information is right)
She also don't have any other details to give.

American Beauty?

As there are tons of movies with the word America or American in them we really need something more about the movie.
