This movie could have worked if someone bothered to edit it. It's like a Girls Gone Wild video with a plot imposed on it --- except that the plot is hard to find. It revolves around a guy named Alan who shows up as a virgin drinker. He doesn't want to party with everyone else, but then he finally gives in, gets loaded and steals the spotlight from everyone else. Viva alcohol!
It's the "everyone else" that makes the movie so bad. There's one guy in a headband who somehow splits into TWO guys with a headband. At some point, I realized that two of the principal partiers looked almost exactly the same. Then, for some reason, a woman gets very angry at a guy because another woman is sitting on his lap. The filmmakers decided that this moment has a lot drama, so they show it over and over. One of the worst moments involves a black guy who spends the entire movie begging a woman for sex. For some reason, the filmmakers think this kind of thing is entertaining. But it isn't. The whole movie is an annoying mess.
