The young dragon Firedrake is tired of constantly hiding in a wooded valley — he wants to show adults what he can do. When people are about to destroy the last refuge of his family, Firedrake, along with the fox Sorrel, secretly goes on a journey in search of a mysterious dragon paradise. They soon meet Ben, a homeless orphan who claims to be able to ride dragons. While the boy and the dragon quickly make friends, the fox tries to get rid of the orphan at every opportunity. However, the three need to learn how to work together, because they are being hunted by the evil monster Nettlebrand, who was created by the alchemist to destroy every dragon on Earth.
