About How To Train Your Dragon

A fifteen-year old Viking named Hiccup lives on the island of Berk, a village that's constantly being attacked by dragons who steal food and set things on fire. Hiccup wants to kill a dragon to prove he's not a whimp, so he takes out a bolas-shooting cannon and shoots a dragon out of the night sky during an attack. The dragon lands in the woods some distance form the village, but no one believes that he hit anything. When Hiccup goes out to search for the dragon, It turns out to be a rare and deadly Night Fury. Hiccup makes an attempt to kill the dragon to take its heart to show it to his father, but ends up releasing it instead. 

Hiccup discovers that the dragon, which he eventually calls Toothless because of his retractable teeth, has ended up trapped in a cove. While sketching the dragon in a book, Hiccup realizes that the dragon is missing its left tail fin, which is why he can no longer fly. After learning that a downed dragon is a dead dragon, Hiccup makes a prosthetic tail fin and fits on Toothless.

Meanwhile, Hiccup's father, Stoick, has signed him up for dragon training with Gobber. At first he's the worst student in the class, which comes as no surprise to his classmates: Astrid, Snotlout, Fishlegs, Ruffnut, and her twin brother Tuffnut. Before long, Hiccup is able to use some things he's learned while working with Toothless to manage the school's practice dragons. When Stoick returns from a failed search for the fabled nest of the dragons, he's surprised to hear that his son is doing brilliantly at dragon training. But Hiccup, as usual, is unable to get around his father's expectations and speak frankly, so he can't explain that his success at dragon school is unlikely to lead to the slaying of any dragons.

When Hiccup subdues a practice dragon, unintentionally earning the privilege of killing it before the entire village, he's horrified and decides to flee with Toothless. However, Astrid follows him to the hidden valley and discovers Toothless. Unable to explain his relationship with the dragon, Hiccup takes her flying, and she's captivated. But they get caught up in a flock of dragons returning to their nest carrying food.The dragons fly inside a mountainous island and drop the food into a pit, which turns out to contain a huge, terrifying, and very hungry dragon that eats the smaller ones if they don't bring enough food. Hiccup and Astrid are shocked to realize that the dragons have been stealing their sheep to keep from being eaten themselves.

Everything goes wrong at the dragon-killing ceremony. Hiccup discards his weapons in an attempt to show the Vikings that dragons only fight to defend themselves, but Stoick and others intervene and the dragon attacks. Toothless comes to the rescue and is on the verge of killing Stoick when Hiccup calls Toothless off. Despite Hiccup's protests, the angry Vikings chain Toothless up. When he ineptly tries to explain, Hiccup lets it slip that Toothless took him to the nest of the dragons, and Stoick resolves to use Toothless to find the nest again.

At the dragons' island, the Vikings break open the side of the mountain in which the giant dragon is trapped. When it comes out, Stoick realizes that he's made a mistake. While Stoick and Gobber prepare to sacrifice themselves to distract the dragon, the kids arrive to join the battle on their newly trained dragons. They do manage to distract the Red Death, but it sets the Vikings' ships on fire. While his comrades keep the Red Death occupied, Hiccup tries to rescue Toothless (who's still in chains) from the burning ship, but they end up under water. After Stock rescues them, Toothless and Hiccup go after the Red Death together.

After defating the Red Death, Hiccup wakes up at home, and Toothless urges him out of bed. Hiccup finds that he lost his left foot in the battle. However, Gobber has made him a new one, ingeniously spring-loaded. With the help of Toothless, they make their way outside, which is full of swooping and frolicking dragons; the Vikings now treat them as pets. Astrid greets Hiccup with a kiss. Supplied by Gobber with a new tail fin prosthetic and saddle for Toothless, Hiccup takes flight with Astrid and his friends as he exults at the new alliance of Vikings and Dragons.
