An army of fox hounds hunt a red fox named STREAK across the Great British countryside. It is the Dark Army, and its leader BAAL is gaining on his prey until his human masters halt his progress, allowing the fox to escape into a vast forest known as Averon. The exhausted fox is later roused by two other foxes, DORAN and TALI, who take him to their den known as Shadow Oak, and their leader KEDEM, who suggests that Streak stay with them until he is fit again to venture out on his own.
Baal and the Dark Army prepare to launch an attack on the forest and all animals willing to harbor the fox who escaped their clutches, whilst the foxes must find a way of defending themselves and the great forest in which they live. Aided only by a mysterious barn owl named CYRIUS, an adventure begins in which the animals of the forest must attempt to unite with each other before Baal and his great army is released.
