Legend has it that a dark monster walks the woods in Alaska. A beast whose scream can freeze a man's heart. A beast with a taste for blood. Now 17-year-old Reese Camden is about to have a camping trip from hell. Stuck in below freezing temperatures, Reese, his sister Rose, and their school friends Deke, Kaori, and Mina, are on a winter survival school trip. It's supposed to be a week of fun and hopefully no frostbite. But when they wake up one morning and find their camp destroyed and their teacher missing, they quickly realize that something is hunting them. And it's only a matter of time until they're all found.
