On the island of Berk, Vikings have always fought off dragon attacks. Hiccup, the clumsy but clever son of Chief Stoick, manages to wound a fearsome Night Fury with one of his inventions. In secret, he finds the injured dragon, nurses it back to health, and forms a bond with it, naming it Toothless. While his father enrolls him in dragon-slaying training, Hiccup realizes that dragons aren’t the enemies they’ve been made out to be. He hides Toothless and discovers a different way to live alongside dragons.
