Captain Jack Sparrow’s ship, the Barnacle, and its up-till-now unshakable crew have suddenly fallen under a sinister spell. While continuing on their quest for the storied Sword of Cortés, the crew is attacked by a monstrous sea creature and then finds its shipmates entranced by an ethereal song and each of them attempts to take the Barnacle in a different direction-and away from the sword’s supposed location. Only Jack seems unaffected by the strange song, but can he both subdue his crew and defeat the mysterious force behind the dark spell?
