Gandalf, and old wizard tries to convince Bilbo to go on an adventure with him. Bilbo declines hastily but invites Gandalf to tea because he felt rude. The next day twelve Dwarves and Gandalf enter his house. They explain to Biblo they intend to go and fight Smaug, the dragon under the mountain to reclaim their lost treasures. Bilbo agrees and decides to go with them. Their band fights goblins and is chased by wargs ont he way to Rivendel, where Elrond reveals even more secrets about the map. They then get separated and Bilbo meets Gollum. With Gollum, Bilbo plays a game with deadly stakes and ends up escaping with a ring that allows the wearer to be invisible. They continue their adventure and encounter giant spiders and eagles. They defeat everything and eventually slay the dragon Smaug. After the dragon is slain, the Wood-elves and Lake-men besiege the Mountain and request compensation for their aid, reparations for Lake-town's destruction, and settlement of old claims on the treasure. However Gandalf warns of an approaching army of golbins and wargs. The men elves and dwarves band together with help from the eagles to defeat the goblins. After the battle, Bilbo takes a portion of his share and returns home.
