It’s Halloween night at the Bowl-o-Rama where Samantha and her friends are having a party. Everyone’s having a great time… until the Chubbies arrive. From the distant planet of Snerd, where sex is outlawed, come the chubbies. A race of grotesque, and horny little creatures, hell bent on global domination by invading your body through any orifice they can find. The party dies and the horror is born when the teens are held captive by the Chubbies and must fight to keep their butt holes tight in this action packed, horror comedy.
