At the beginning Gandalf and dwarves show up at Bilbo's house to ask if he would join them in reclaiming their home from the dragon Smaug. At first, Bilbo didn't want to, but in the end, he decided to go.
Thorin and company at your service.
We would like you to come with us to reclaim our home.
Not far into the story the group is captured by goblins and are about to be killed. However Gandalf saves them just in time.
Ahhh this is the orcrist sword
These swords killed goblins
Well, the dwarves are captured Bilbo is in a cave where he meets Gollum and finds a magic ring.
Well, traveling through the Mirkwood forest they see light and go to it but goes away as soon as they get close. Then they get caught by spiders then elves which Bilbo has to escape them from.
I can't see anything
That boat would have helped
Is that a light?
Bilbo escapes the dwarves from the elves and they go to Lake-town, then to the mountain where they find the hidden door that Biblo goes in and meets Smaug. He runs away back to the tunnel that later gets closed off, Meanwhile back in Lake-town Smug attacks, but gets killed.
It's so cold
How much longer?
I don't feel so good
Has anyone seen the Arkenstone?
After they find out Smaug is dead they go back to protect the treasure from everyone. But there is one thing that Thorin can't find the Arkenstone, because Bilbo has it and he gives it to Bard to use.
The battle of 5 armies is a big fight. Of course, they do end up winning but that is only with the help of Gandalf the eagles and Beorn. Even though they won sadly Fili Kili and Thorin do not make it.
If we do this there is no doubt that we will get some gold
Look the eagles
During the whole battle, Bilbo is using his ring to hide. After the battle when he gets home there is an auction happening of his things.
