Ierland, negende eeuw. Brendan, een opgewekte en goedlachse weesjongen van 12 leeft in de abdij van Kells dat verscholen ligt in een verlaten groene vallei. Hij wordt er streng opgevoed door zijn oom, de abt Cellach, die de abdij met ijzeren hand leidt. Op een dag ontmoet hij de oude broeder Aidan. Deze ietwat vreemde man is een meester in het illustreren en houdt een buitengewoon, nog onvoltooid boek in bewaring. Enthousiast en begeesterd door deze ontmoeting laat Brendan zich meeslepen door de lokroep van de creativiteit en verbeelding. Hij heeft slechts nog één doel voor ogen: zelf meester illustrator worden en het waardevolle boek van Kells afwerken. Maar om dit te doen, moet Brendan zich buiten de muren van de abdij begeven, waar grote gevaren op hem wachten... Zal Brendan er in slagen om het boek te voltooien, en zullen de abdijbewoners de steeds groter wordende dreiging van de Vikingen kunnen weerstaan?
Nee, helaas is Brendan, Het Geheim van Kells nog niet beschikbaar op Netflix in Nederland.
