As Hiccup fulfills his dream of creating a peaceful dragon utopia, Toothless' discovery of an untamed, elusive mate draws the Night Fury away. When danger mounts at home and Hiccup's reign as village chief is tested, both dragon and rider must make impossible decisions to save their kind.
When Hiccup discovers Toothless isn't the only Night Fury, he must seek "The Hidden World", a secret Dragon Utopia before a hired tyrant named Grimmel finds it first.
