There is a legend among the animals. Long ago, a great tiger, known as Arznel, led an uprising against the humans, in a bid to save the world from destruction. But Arznel was defeated, captured and never seen again. Hope remains, that one day he will be free, and the great revolution can begin anew. But where is Arznel? And who can rescue him? Dreamer, a young fox, embarks on a journey through the Irish countryside, in search of a new home. With him are Victor, the badger, and Rush, the hare. The three friends take refuge in the beautiful nature sanctuary of Lough Ine. Here, they discover the legend of Arznel, but before they can do anything to help him, they must first struggle with love, faith, adolescence, inter-species racism and… poachers.
