Bastian is a young boy who lives a dreary life being tormented by school bullies. On one such occasion he escapes into a book shop where the old proprieter reveals an ancient story-book to him, which he is warned can be dangerous. Shortly after, he "borrows" the book and begins to read it in the school attic where he is drawn into the mythical land of Fantasia, which desperately needs a hero to save it from destruction.

The independent and lonely hunter Martin David is hired by the powerful biotech company Red Leaf to hunt down the last Tasmanian tiger. Red Leaf is interested in the DNA of the animal and Martin travels to Tasmania alone. He poses as a researcher from a university and lodges in the house of Lucy Armstrong. Martin learns that Lucy's husband has been missing for a long time and he befriends her children, Sass and Bike. When Martin goes to the village, he has a hostile reception from the locals. Along the days, Martin spends his days in the Tasmanian wilderness chasing the Tiger and becomes closer and closer to the Armstrong family. But Red Leaf wants results no matter the costs.
