It's about a hobbit named Bilbo Baggins who gets roped into going on an adventure with dwarves by a wizard named Gandalf. He's very happy not going on adventures, but he still manages to find himself being whisked into one. All to reclaim the dwarven treasure from the treasure hoarding dragon, Smaug.
