Massacre (the Musical) (2008)

Discordia Doren's best friend, Carmella Brigante, thinks she should loosen up and have a little fun. So, she encourages the prudish Catholic schoolgirl to tag along with her and a group of hedonistic teenagers to a cabin in the woods for some drinking, drugs and debauchery. But they are not alone. Something evil lurks in the woods surrounding the cabin. Something that recognizes Discordia for what she truly is.
