Izzy and her friends are SO EXCITED about their school trip. They're going camping and there'll be marshmallows and no washing and everything. But then WEIRD things start happening! There are howling sounds at night, and some sausages have gone missing, and it's nearly a full moon...

But it's when they see their new teacher's hairy legs that they KNOW! There's a werewolf on the school trip and they're all DOOMED!
