Every cedar holds a spirit. Every spirit longs for home.
When a young Japanese cedar sapling is transported to a Canadian zoo for a new “Trees of the World” exhibit, no one realizes it carries with it a kodama—an ancient tree spirit torn from its home. As the cedar begins to wither, strange phenomena ripple through the zoo, and a girl named Maureen O’Neil decides to find out why. With her mother's support, Maureen challenges the botanist who brought the tree overseas. A violent storm reveals the truth so, together, child, mother, and scientist undertake a journey to restore nature's balance.
