King Iubdan, ruler of the Little People, believes he is the most powerful king in the world, but Ossian the court minstrel knows something that no one else does. He has discovered the kingdom of the Big People. When the two rulers meet, it seems unlikely that they will ever learn to get on. Luckily their children have other ideas, and what happens next helps to explain why the Irish people are like they are today.
