As the son of a Viking leader on the cusp of manhood, shy Hiccup Horrendous Haddock III faces a rite of passage: he must kill a dragon to prove his warrior mettle. But after downing a feared dragon, he realizes that he no longer wants to destroy it, and instead befriends the beast – which he names Toothless – much to the chagrin of his warrior father.
A scheming raccoon fools a mismatched family of forest creatures into helping him repay a debt of food, by invading the new suburban sprawl that popped up while they were hibernating – and learns a lesson about family himself.
Hiccup and Toothless go on an exciting adventure and discover an island of new dragons.
