Bilbo cracked his head on a stone being left behind in the cave, waking up he wandered around lost until he found a golden ring which he put in his pocket coming upon a creature named Golem.
Golem and Bilbo played a game of riddles where if Bilbo wins he gets showed the way out but if Golem wins he eats Bilbo. Bilbo wins with a clever riddle. Bilbo escapes him with the rings power to turn him invisible.
Bilbo leaves the cave meeting with the dwarfs and Gandalf facing off against wolves until saved by eagles. After that they went through Mirkwood becoming captured by giant spiders and wood elves saved by Bilbo's ring.
They reach Lake town meeting a strong hunter bard. They found themselves at a door on top the mountains where Bilbo met Smaug seeing a weak spot in his armour sending a bird to report to Bard.
Smaug in a rage was burning down Laketown. After the bird told Bard about the weak spot it caused Bard to kill Smaug. This created conflict over the treasure.
Five armies battled which causes the loses of some of the dwarfes. Bilbo gets his share of the treasure and returns to his quaint hobbit hole finding it plundered because people presumed him dead. Bilbo forever changed by this journey.
