Twin brothers River and Terran discover a portal to a hidden forested world attacked by parasitic fungi, dark shamans, and serpents. Along with an assembled band of unlikely misfits that includes coyotes, whitetail deer, wood thrushes, and fox squirrels, they must unlock their unique powers to control the elements of earth, air, fire and water, and save the forest before the evil they've uncovered can spill back into their own world.
