The Premise
The film continues the adventure of the title character Bilbo Baggins as he journeys with the Wizard Gandalf and thirteen Dwarves on an epic quest to reclaim the lost Dwarf Kingdom of Erebor. Having survived the beginning of their unexpected journey, the Company continues East. After escaping capture by the dangerous Woodland Elves, the Dwarves journey to Lake-town, and finally to the Lonely Mountain itself, where they must face the greatest danger of all — a creature more terrifying than any before, which will test not only the depth of their courage but the limits of their friendship and the wisdom of the journey itself — the Dragon Smaug.
