Deep in an ancient forest, young Taru feels like a misfit among her tribe of hunter-warriors. As she tries to make her mark in the adult world, she finds herself marginalized—as much for her naïveté as for her radical ideas, which are dismissed as nonsensical. Meeting Hana, a young human with a mysterious past who has been taken prisoner by Taru's own tribe, provides her with both solace and an opportunity to find her own way. When Taru's village is once again attacked by giant beasts, the unlikely pair will work together to try to understand the uncontrollable and deadly force that threatens them.
