In a time of superstition and magic, when wolves are seen as demonic and nature an evil to be tamed, a young apprentice hunter, Robyn (voiced by Honor Kneafsey), comes to Ireland with her father to wipe out the last pack. But when Robyn saves a wild native girl, Mebh (voiced by Eva Whittaker), their friendship leads her to discover the world of the Wolfwalkers and transform her into the very thing her father is tasked to destroy.
