The Hobbit

Gandalf marks Bilbo's door, thirteen dwarves arrive for supper, and Thorin reveals the quest: reclaim the Lonely Mountain from Smaug. Bilbo faints but secretly longs to go.

Bilbo runs to join the dwarves, the company encounters three trolls (Bert, Tom, and William) who capture them. Gandalf returns and tricks the trolls into arguing until dawn, turning them to stone.

The company rests in Rivendell with the elves. Elrond reads the moon-letters on Thorin's map, revealing: 'Stand by the grey stone when the thrush knocks, and the setting sun with the last light of Durin's Day will shine upon the key-hole.'

The company crosses the Misty Mountains in a storm, is captured by goblins, escapes with Gandalf's help, and Bilbo is separated in the dark. He finds a ring, wins a riddle game against Gollum, and escapes invisibly.

The company escapes pursuing goblins and wargs by climbing trees, rescued by eagles. They shelter with Beorn, a skin-changer who can become a bear, and are sent on to Mirkwood.

Lost and starving in Mirkwood, the company is captured by giant spiders. Bilbo, using the Ring, names his blade Sting and rescues the dwarves alone. The dwarves are then captured by Wood-elves. Bilbo engineers their escape in barrels floated down the river.

The company arrives at Lake-town and is received as heroes. They travel to the Lonely Mountain, find the secret door, wait for Durin's Day, and Bilbo is sent alone into Smaug's lair.

Bilbo enters Smaug's lair, steals a cup, flatters the dragon into revealing his weakness — a bare patch on his left breast — and discovers Smaug has gone to attack Lake-town.

Smaug destroys Lake-town. Bard kills Smaug with the Black Arrow, warned by the thrush. An army of men and elves marches on the Lonely Mountain. Thorin, afflicted by dragon-sickness, fortifies and refuses to share.

Bilbo secretly gives the Arkenstone to Bard and the Elvenking as a bargaining chip. Thorin discovers this and nearly throws Bilbo off the walls. The Battle of Five Armies: Thorin mortally wounded, dies making peace with Bilbo. Bilbo returns home to find himself declared dead.
