Animated feature based on the ancient Celtic tale of Brendan and the secret of Kells. Twelve-year-old Brendan (voiced by Evan McGuire) lives a quiet life at the Kells monastery with his uncle, Abbott Cellach (Brendan Gleeson) - but this changes with the arrival of the charismatic Brother Aidan (Mick Lally), a master illuminator who takes Brendan under his wing and teaches him his ancient art. In order to finish the magnificent book, Brendan must overcome his deepest fears on a journey that will take him beyond the abbey walls for the first time. In the enchanted forest beyond, he meets the good fairy Aisling (Christen Mooney), a mysterious young wolf-girl who rescues him from wolves and helps him to complete his dangerous and top-secret quest, even as the Viking hordes close in around them.
