Set 1,300 years after the events of How to Train Your Dragon, dragons are now just a legend to the modern world. When a geological anomaly opens an immense, miles-deep fissure in the Earth's surface, scientists from all over the world gather at a new research facility to study the mysterious phenomenon. Soon a group of misfit kids, brought to the site by their parents, uncover the truth about dragons and where they've been hiding -- a secret they must keep to themselves to protect what they've discovered.
Tom and Jun encounter unexpected dangers and are separated while exploring the Hidden Realm of dragons. Tom introduces Jun to the dragon world, and Jun bonds with a dragon of her own - Wu and Wei.
