Eighteen-year-old Adam Rowan is glamping across America with his little brother and cousin in what should be a fun family excursion; but instead, it's turned into a nightmare because the cute girl he just met blew up the diner they were in with her brain. Isn't that always the way? When the sinister Brute Squad catches up to Misty, the Rowans team up with their new friends to go after them to help her bring the whole organization down. But first, she has to survive Halloween.
