In the special Halloween flick (don't miss the full trailer!), all hell breaks loose at spoiled teen Madison's sweet 16 party when a serial killer, who happens to be the father of Madison's new found enemy Skye, arrives on the scene. Having "stolen" the birthday girl's boyfriend, Skye is now the target of humiliation of the queen bee and her gaggle of friends. Only, in our exclusive clip below, it seems like the (fire extinguisher) joke is on Madison's bestie.
