Jack Sparrow feels the winds of ill-fortune blowing even more ardently when deadly ghost sailors led with his old nemesis, the evil Capt. Salazar, escape by the Devil's Triangle. Jack's only real hope of survival is based on seeking the mythical Trident of Poseidon, but he must invent an alliance with a gorgeous and dazzling astronomer and a headstrong young man at the British navy to believe it is.
