[4][15][16] Wolfwalkers follows the story of Robyn Goodfellowe, a young apprentice hunter who arrives in Ireland with her father during a time of superstition and magic to wipe out the last wolf pack.

While exploring the forbidden lands outside the city walls, Robyn befriends a free-spirited girl, Mebh, a member of a mysterious tribe rumoured to have the ability to turn into wolves by night.

As they search for Mebh's missing mother, Robyn uncovers a secret that draws her further into the enchanted world of the Wolfwalkers and risks turning into the very thing her father is tasked to destroy.

The film stars the voices of Honor Kneafsey, Eva Whittaker, Sean Bean, Simon McBurney, Maria Doyle Kennedy, Tommy Tiernan, Jon Kenny and John Morton.

[17][18] In Ireland in 1650, the residents of Kilkenny work to clear the nearby woods under orders from the authoritarian Lord Protector, putting them at odds with a local wolf pack.

The next morning, while working at the scullery, Robyn is drawn into the Lord Protector's chambers by a mysterious voice coming from a concealed cage, but is soon ushered out by the head maid.

Upon returning to Kilkenny, Robyn infiltrates the Lord Protector's manor, where she finds Moll's wolf form inside the cage.

The Lord Protector, seeking to restore control of the town, assures the townspeople that he can tame the wolves, and by extension, nature itself.

Robyn and Bill return to the den and help Mebh revive Moll, and accept her invitation to stay with the pack and embrace their new identities as Wolfwalkers.

[19] The film is an original concept that was created by Moore and Stewart, and its animation uses a unique 2D style alternating between a woodblock aesthetic and loose expressive line work.

[15][16] Moore's frequent collaborators, Bruno Coulais and folk group Kíla, provided the film's original score.

The town and its inhabitants are drawn in a style inspired by 17th century woodcuts using thick lines and angular, geometric shapes.

[27] The art style of the forest characters also includes intentional pencil construction lines which would normally be removed by a clean-up department.

McNamara's team constructed a 3D forest environment with the virtual reality painting software Quill with further refinement and stylisation done in Blender.

[29][30][31] Each frame of the CG animation was then printed out in magenta which the artists drew over with pencil and charcoal to match the film's hand-drawn look.

[33][34] The theatrical release in Ireland was planned for the same day as the UK, but was delayed until later in the year due to the enforced closure of cinemas across the country in response to the COVID-19 pandemic.

The website's critical consensus reads, "A mesmerizing Celtic-inspired adventure, Wolfwalkers offers an epic ethereal fantasy matched by profound philosophies and stellar voice work.

[41] Peter Debruge of Variety wrote: "In the decade since Kells, it's not just the technological advances that make Moore's latest so impressive, but the rapidly changing cultural conversations as well.
