A group of teens attend an epic rave party only something goes wrong in the night and each one of them is duplicated. A semi-sober few of them realize what has happened and convince a few more that they have to kill their duplicates. There is never a valid reason given for the phenomena but the main story seems to focus on one guy who is trying to get his girl back. He blew it with the first one so he decides to try a different strategy with the duplicate. Does the entire plot sound kind of lame? It is. Save for a couple of good scenes where people are killing their other selves it's just mostly watching a bunch of spoiled rich teens having a big expensive party.
This girl loved herself a little too much.
