Thrust into an all-new adventure, a down-on-his-luck Capt. Jack Sparrow feels the winds of ill-fortune blowing even more strongly when deadly ghost sailors led by his old nemesis, the evil Capt. Salazar, escape from the Devil's Triangle. Jack's only hope of survival lies in seeking out the legendary Trident of Poseidon, but to find it, he must forge an uneasy alliance with a brilliant and beautiful astronomer and a headstrong young man in the British navy.

Immediately after the events of The Desolation of Smaug, 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.
