Hiccup (Jay Baruchel), is the son of the Leader, Stoick the Huge (Gerard Butler), on the island of Berk. Hiccup’s village is constantly plagued via “pests” within the type of various dragons, who raid the village and thieve from their stock of sheep. Hiccup, not able to fight the dragons, as an alternative works as an apprentice to the iron smith, Gobber the Belch (Craig Ferguson).

One evening all through a dragon raid, Hiccup pulls out a launching contraption in an attempt to end up himself and kill the by no means-ahead of-noticed Night time Fury dragon. He hits it, but no one else within the village is round to see it. Attempting to get proof, Hiccup travels into the forest the place the dragon may have fallen. He comes to a small canyon and sees the elusive Night time Fury, tangled in his net. After suffering from himself, Hiccup can’t convey himself to kill the helpless dragon and units him free.

Back on the village, Stoick, with the insistence of Gobber, enrolls Hiccup into dragonfighting elegance with the other Viking adolescence of age: Astrid (The us Ferrera), Snotlout (Jonah Hill), Fishlegs (Christopher Mintz-Plasse), and the twins Tuffnut and Ruffnut(a boy and a lady) (T. J. Miller and Kristen Wiig). In the meantime, Stoick leaves with a search party of Vikings to are searhing for out the Dragon’s Nest, as some way to wipe them out and finish the apparent war. The first day of dragon training is going as expected for Hiccup; he’s outmatched and missing confidence. After being advised that dragons are vicious and at all times go for the “kill shot”, Hiccup curiously returns to the canyon. The Night time Fury, still inexplicably trapped within the canyon, again allows Hiccup to observe him. Hiccup then notices that the dragon is missing a tail wing from the previous crash landing, leaving him not able to fly properly.

After understanding that he can befriend the dragon, Hiccup comes to a decision to get started out gazing the dragon, whom he names Toothless. Hiccup sooner or later fashions an artificial tail wing, allowing Toothless to fly, but simplest with Hiccup’s aid. Meanwhile, back in Hiccup’s dragonfighting classes, Hiccup starts to have great success. Using the observations from Toothless, Hiccup manages to have superior control over each and every dragon in coaching to the amazement of everybody and the chagrin of Astrid who turns into in an instant suspicious. In the meantime, Astrid starts to get jealous of Hiccup’s success and suspicious of his escapes into the forest.

Whilst Stoick and his army go back they are bruised and battered, coming again with only one send, nowhere close to having discovered the nest. His spirits are lifted, however, whilst Gobber and others begin congratulating him on Hiccup’s luck in dragon training. Feeling a chance to bond together with his son, Stoick luckily honors Hiccup along with his own Viking helmet (produced from part of his mom’s breastplate). Given that Hiccup is in good status to be the top of the class and feature the dignity of slaying a dragon, he begins to really feel torn for his friendship with Toothless and the danger to make his father proud.

Hiccup crumbles to the power and makes a decision to depart Berk with Toothless. Astrid follows him to their hideout and discovers Hiccup’s friendship with the dragon. She attempts to run back to the village, however Toothless kidnaps her and Hiccup asks for a possibility to explain. They take her for a journey and Astrid begins to see how amazing dragons really are in addition to Hiccup’s odd talents. All over their flight, they get stuck in a herd of dragons wearing food and practice them to their nest. There, they uncover that the dragons scouse borrow food to feed a far higher and extra threatening dragon that eats them if they don’t supply enough food. Once they depart, Astrid wants to inform the village of the nest’s area, but Hiccup makes a decision towards it in order to offer coverage to Toothless and Astrid has the similar opinion to stay quiet.

The subsequent day to come, all the way through Hiccup’s battle with the Nightmare, he throws down his guns and tries to show everyone that dragons aren’t as dangerous as they seem. Stoick shouts to prevent the struggle ahead of Hiccup can continue, and the Nightmare attacks Hiccup in response to Stoick’s rage. Toothless, from his hiding position on the island, hears Hiccup scream and races off to Berk to save loads of him. Just before the Nightmare can finish Hiccup off, Toothless comes in and defeats the Nightmare.

Hiccup pleads Toothless to escape, however he ignores him, fearing that the other Vikings pose a threat to Hiccup. Toothless virtually kills Stoick, but Hiccup begs him to forestall, and Toothless right away turns into more docile. In this peaceful state, Toothless is instantly overpowered and captured. Stoick confronts his son angrily at finding out approximately his son’s friendship with a dragon. Hiccup accidentally tells him that he has been to the nest, and Stoick comes to a decision to make use of Toothless to steer them there. Hiccup begs him to not harm Toothless and warns them of the giant dragon that they likely stand no chance towards, however Stoick ignores him.

The Vikings set sail with Toothless chained. Again at Berk, Astrid comforts Hiccup and asks him what he is going to do. Hiccup makes a decision to use the dragons that the Vikings use for dragonfighting observe to fly to the nest. In the meantime, Astrid has accumulated Tuffnut, Ruffnut, Fishlegs and Snotlout to help. Each mount at the dragons and induce after the Vikings.

As the other Vikings arrive, they prepare for struggle, however all the dragons flee the island. Stoick discovers the even bigger dragon which sets the entire boats on hearth, including the one Toothless is chained up on. Hiccup and the others arrive, and even as he goes to unfastened Toothless, the others try to distract the enormous dragon. The boat collapses and Toothless sinks, still chained. Hiccup attempts to unfastened him however nearly drowns. Stoick saves his son and jumps back in to shop rather a lot of Toothless. Hiccup and Toothless then shoot on the giant dragon’s wings and lead it into the air. They then dive towards the ground and set fireplace to the dragon’s insides. The giant dragon attempts to tug up, however the shots fired in the past have torn holes in his wings, sending him crashing into the ground and exploding in a thunderous inferno. After crashing into the bigger dragon’s tail, Hiccup is knocked out and falls off Toothless and into the fire. Toothless dives in to avoid wasting him, regardless of his saddle damaged and synthetic tail destroyed. Stoick searches the rubble for his son and only finds Toothless. To start with everybody thinks Hiccup died within the hearth but Toothless unearths that he had wrapped Hiccup up in his wings to defend him.

Hiccup reawakens in his house and reveals Toothless by approach of his bedside. He also reveals that his left foot have been lost within the battle with the giant dragon, changed with a prosthetic via Gobber the utilization of the boy’s designs. With Toothless’ help, Hiccup slowly makes his method outside and sees that Vikings have invited dragons into the village. Everyone welcomes Hiccup back as a hero. Astrid then appears and kisses Hiccup. Hiccup is then given new apparatus for Toothless constructed through Gobber. Hiccup and Astrid experience their dragons in the course of the newly reformed Berk as the alliance among the Vikings and dragons begins.
