Mitzy and Bobby are dating. Mitzy's parents go out of town and she throws a slumber party. Booze and board games soon grow boring for Powder, Biggie, Chi Chi and even Mitzy. The Girlz google the Legend of Bloody Mary and call her name three times in the bathroom mirror. Nothing happens. Powder and Biggie head outside for a smoke session and are ambushed by Bobby's friends. But where's Bobby? Hell, where's Chi Chi? This party soon turns killer, as Bloody Mary appears through every mirror in the house. Will anyone make it out alive? How can she be stopped? Well she can't kill a virgin. Oh well, I guess they're all frickin screwed.
