The film’s action takes place during the 13th century, on an island in Ireland on the edge of the world. A small group of monks embark on a pilgrimage where they face, on the one hand, the people who have been living in the tribes for centuries, on the other hand, with the increasing power of the Norman invaders. Escorating the most precious object of their monastery in Rome, the way of the monks is seen through the eyes of a novice and a mute little boy with a violent past. The more obvious the fact that it transports a precious object, the more dangerous it becomes to the east. The monks realize, quite late, however, that in that world of ancient superstitions, the purpose that binds them may be the one that leads them to death.
