There is a large island out in the middle of the sea. Humans live on one side while the rest is uncharted wilderness inhabited by Eevees and Eeveelutions. Juniper just wants to be a normal Leafeon living in the Forest Tribe but he was caught in a fire as a kitten. Missing his tail, he struggles training to catch prey and fight for the tribe. When a strange visitor arrives and brings an army with her, it might only be Juniper and his friends that can stop her.
