I was watching a movie last week
And It was on syfy
It was a horror or thriller movie
It was a group of highschoolers
And the preps/jocks was picking on the outcasts and the outcasts had enough of it, so at the preps/jocks Halloween party those outcasts drugged all of them and chained them together and killed on with a cow killing thingy, another had to chop another persons fingers off, one was killed with needles, another I think was shot, twards the end of the movie there was one who excaped and called the cops then cops showed up and all of the outcasts killed each other

The Final
