In Big Creek, Alabama, just outside Mobile, a family of foxes compete against coyotes on Farmer Reynolds' farm near the Escatawpa River. The fox family has a treaty. If the foxes don't eat the chickens, the farmers' dog and cat will steer hunters from the fox den. Mistletoe, a fox from last year's litter, is keen on upholding that treaty and protecting his family.

But Mistletoe is up against a strong and wily foe. Coyote Thorn and his pack intend to claim the chickens for themselves, and they are prepared to fight if the foxes choose to warn Farmer Reynolds of their plans. 

With the help of the majestic stag, Ahwi, and a magical oak tree portal to another world, Mistletoe gains a powerful tail that launches fireballs. Can his newfound power and bravery end the battle between the foxes and coyotes?
