Rhydian is a foster kid, and until he starts at Maddy's school has never met another wolfblood and thought he was the only one. He's wary of Maddy and she's fearful of him. Not realising that he has been fostered, she thinks his family are invading her territory. When she finds out the truth she tries to explain their heritage to him, but is still worried he will give them all away.
Maddy has kept her wolfblood secret from her best friends Tom and Shannon her whole life, which makes things difficult when Shannon becomes obsessed with the idea there is a beast on the moors, not realising it's likely to be Maddy's mum or dad!
Meanwhile, Shannon thinks she finally has proof of the "beast on the moors". She has a photo of a wolf and puts up posters of it all around the school. When her proof mysteriously goes missing Shannon is distraught and the laughing stock of the school so she goes on a mission to get a new photo. After her parents' revelation Maddy suddenly realises she is in terrible danger, as the wolf in the photo is a wild wolfblood.
Overnight, the exhibition is trashed, pictures are ripped, and Katrina's mum's jacket, which she brought in as her project, has been ruined - and she didn't know she'd borrowed it!) Jimi spreads rumours that it was Rhydian, so Maddy, Shannon, and Tom go on the hunt for the real vandal. Who has a grudge against Rhydian?
Under extreme pressure in the first exam, the stress gets too much for Maddy and she starts to transform. Rhydian senses this and causes a distraction by breaking the fire alarm, which only makes the situation with Shannon and Tom even worse.
