Bilbo Baggins gives Frodo the Ring. Gandalf comes for a visit and realizes what the ring is. He then asks Frodo to bring it to Rivendell so that he can bring it to Mount Doom to destroy it.

Frodo doesn't want to carry this ring, especially not after the stories Gandalf tells Frodo of the dangers this ring brings.

Frodo goes to Aragorn's wedding. He also goes to Sam's wedding, who is elected to be the mayor. The others are also living the lives they lived before, but this time they are more united. Basically, they are able to lead their normal lives, except for they're able to do it even with the tragedies and differences they've faced.
