Summer 1998: three boys, three girls, one hell of a night. Turn the music up and let the blood flow as ritual sacrifice becomes the ultimate party game. Alexandra Daddario, Maddie Hassan and Johnny Knoxville star in one house party that's ready to make the headlines. Hail Satan! Delightfully madcap, zany and enjoyable, with exceptionally memorable and entertaining characters, this horror-comedy will bring the (satanic) house down!
