Jamie is awakened as Kat is having one of her nightmares, and sees the room trashed and her eyes glowing like an animal's. Jamie 's new friend Jasmin, the youngest daughter of the zoo manager, thinks Kat might be a were-tiger. Their mom has Kat checked out by a doctor, but the still-suspicious Jamie and Jasmin put some raw meat in her room to see if the previously vegetarian Kat has changed her eating habits.

15 year old Katrina's carefree life in rural Australia is upended when her father's work sends him overseas, and she and her little brother Jamie are sent to the big city of Perth to live with their mother, whom they have not seen for several years. She is the veterinary scientist for a zoo, and seems more interested in the animals than in her children. Then Kat starts to experience strange nightmares.
