If other islands worry about pests like rats or insects, the island of Berk worries about something much bigger: dragons.
Dragons are vicious creatures. They steal sheep for food and destroy homes and crops with their fire. Every attack is a reminder that life in Berk is dangerous and unpredictable.
But Berk is home to the toughest and meanest Vikings. They don’t back down from anything, not even fire-breathing, high-flying dragons. The people of Berk are fearless. When a dragon appears, they fight it, capture it, punch it, or kill it.
Hiccup (Mason Thames) is the son of the Viking chief, Stoick the Vast (Gerard Butler). As the chief's son, everyone expects great things from him. But Hiccup doesn’t fit the Viking mold. He’s thin, weak, clumsy, and far from fearless. He often ruins whatever he touches, much to the disappointment of his father.
His peers don’t see much value in him either. Snotlout (Gabriel Howell), Fishlegs (Julian Dennison), Ruffnut (Bronwyn James), and Tuffnut (Harry Trevaldwyn) each have unique strengths and bravery that makes them useful in battle. Even Astrid (Nico Parker), Hiccup’s crush, is a fierce and skilled warrior. She’s easily the best Viking of their generation.
Still, not everyone has given up on him. Gobber (Nick Frost), Hiccup’s mentor, sees potential in the boy. He believes that maybe Hiccup doesn’t need to be a typical Viking. Maybe he just needs to stop pretending to be someone he’s not and start embracing who he really is: a thinker, a builder, a problem-solver. Someone who sharpens swords, creates strange gadgets, and invents new things.
Then one day, everything changes.
Hiccup encounters a trapped dragon. Not an ordinary dragon, but a Night Fury. Night Furies are known to be incredibly fast, dangerously powerful, and extremely rare. According to Viking law, if you see one, you must kill it on sight.
But Hiccup can’t do it. He raises his knife, then lowers it. Instead of killing the Night Fury, he sets it free.
The dragon, however, can’t fly away. Hiccup soon realizes that the Night Fury’s tail fin is damaged, making flight impossible. Hiccup decides to do something crazy, he builds the dragon a prosthetic tail fin.
Before he can test it, though, he must first do the impossible: earn the dragon’s trust.
As Hiccup spends more time with the dragon he named Toothless, he realizes something that could change everything: dragons might not be the enemy after all. They’re not mindless beasts. In actuality, they’re intelligent and emotional creatures.
This revelation forces Hiccup to question everything his father and his entire community believe. Maybe they’ve been wrong about dragons after all.
