When Finn comes across a car accident, little does he realise his life is about to change forever. The huge, injured animal he discovers is no dog - but a wolf, escaped from the circus. Finn is bewitched. Instinctively, he knows he must save the wolf, Lupa, and prevent her return to the cruel circus. Where to hide the wolf, and how to feed her, are just the beginning of Finn’s problems. For the sinister circus clown, Cackles, is hot on their trail and will stop at nothing to get Lupa back. But Cackles doesn’t even like wolves, so why is he so determined to get her? In a race against time to save Lupa, Finn gets help from unlikely quarters. But will it be enough?
