When Queen Maeve threatens to conquer the ancient land of Kells with evil sorcery, four brave warriors: Rohan, Angus, Ivar and Princess Deirdre of Kells call upon their elemental forces of Fire, Earth, Water and Air to become the Mystic Knights of Tir Na Nog and defend Kells from Maeve's cruel magic and monsters. An inspiring show with an uplifting message, great fun for kids. I particularly like the title music.
