Immediately after the activities of The Desolation of Smaug, Bilbo and the dwarves attempt to guard Erebor's mountain of treasure from others who claim it: the men of the ruined Laketown and the elves of Mirkwood. Meanwhile an army of Orcs led by Azog the Defiler is marching on Erebor, fueled by means of the rise of the darkish lord Sauron. Dwarves, elves and guys have to unite, and the hope for Middle-Earth falls into Bilbo's arms.
