A sudden attack by Wulf, a clever and traitorous lord of Rohan seeking vengeance for the death of his father, forces Helm Hammerhand, the King of Rohan, and his people to make a daring last stand in the ancient stronghold of the Hornburg.

Following Smaug's attack on Laketown, Bilbo and the dwarves try to defend 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 the rise of the dark lord Sauron. Dwarves, elves and men must unite, and the hope for Middle-Earth falls into Bilbo's hands.
