Approaching his 111th birthday, the hobbit Bilbo Baggins begins writing down the full story of his adventure 60 years earlier for the benefit of his nephew Frodo. This connects The Hobbit with The Lord of the Rings movie 10 years earlier which had a similar scene. Long before Bilbo's involvement, the Dwarf king Thrór brings an era of prosperity for his kin under the Lonely Mountain, far to the East, until the arrival of the dragon Smaug. Destroying the nearby town of Dale, Smaug drives the Dwarves out of their mountain and takes their hoard of gold. Thrór's grandson Thorin sees King Thranduil and his Wood-elves on a nearby hillside, and is dismayed when they take their leave rather than aid his people, resulting in Thorin's everlasting hatred of Elves.
Thorin and his company are being pursued by Azog and his Orc party following the events of the previous film. They are ushered along by Gandalf to the nearby home of Beorn, a skin-changer who can take the form of the bear. That night, Azog is summoned to Dol Guldur by the Necromancer, who commands him to marshal his forces for war. Azog then delegates the hunt for Thorin to his son Bolg. The following day, Beorn escorts the company to the borders of Mirkwood, where Gandalf discovers Black Speech imprinted on an old ruin. This coincides with a telepathic message from Galadriel urging him to investigate the tombs of the Nazgûl. He warns the company to remain on the path and leaves them. Upon entering the forest they lose their way and are ensnared by giant spiders. Bilbo then sets about freeing the dwarves with the help of his recently acquired invisibility ring. He subsequently drops the Ring and first begins to understand its dark influence after he brutally kills a centipede-like creature to retrieve it.
Bilbo and the Dwarves watch from the Lonely Mountain as the dragon Smaug sets Laketown ablaze, and its people flee. Bard the Bowman breaks out of prison, and eventually kills Smaug with the black arrow brought to him by his son Bain. Smaug's falling body crushes the fleeing Master of Laketown, who was escaping Laketown on a boat laden with the town's gold. Bard reluctantly becomes the new leader of the Laketown people as they seek refuge in the ruins of Dale, while Legolas travels to investigate Mount Gundabad with Tauriel. Thorin, now struck with "dragon sickness" over the vast treasure in the mountain, searches obsessively for the Arkenstone, which Bilbo had previously found but kept hidden. Thorin, hearing that people have come to Dale, orders the entrance of the Lonely Mountain sealed off.

The island of Berk is a remote Viking village, from which dragons periodically steal livestock. Hiccup, the awkward son of the village chieftain, Stoick the Vast, is too small to fight the dragons and instead fashions mechanical devices under his apprenticeship with Gobber the blacksmith, though his inventions often backfire. During one attack, Hiccup believes he has shot down a Night Fury, an extremely rare and dangerous dragon. Hiccup later finds it in the forest trapped in his bolas, but finds that he can't bring himself to kill the dragon and instead sets it free. Stoick assembles a fleet to find the dragons' nest, leaving Hiccup in a dragon-fighting class taught by Gobber. Hiccup returns to the forest to find the Night Fury still there, and realizes it is unable to fly properly because of its crippled caudal fin. Hiccup gradually tames the dragon and gives it the name "Toothless", for its retractable teeth. Hiccup makes a harness and prosthetic fin that allows him to guide the dragon in free flight. By studying Toothless' behavior, Hiccup becomes proficient in subduing the captive dragons during training. Stoick's fleet arrives home unsuccessful, but he is cheered by Hiccup's unexpected success.
