When a group of marine biologists crash land in the Bermuda Triangle, they realize they have stumbled into the lost city of Atlantis. But they quickly discover the city isn’t friendly, and its humanoid inhabitants are planning worldwide domination using the piles of weapons and technology that have fallen through the Triangle over the centuries.

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.
