Plot
When Sarah Black, curator at the Caribbean Naval Museum, receives a package from a mysterious messenger, she is unwittingly drawn into an ancient conflict. Inside the package she finds an artifact, and instantly assailants descend on the museum to rob her. The artifact is stolen. Sarah lowers her head in disbelief as she realizes that again she is falling headfirst into a nightmare from the deep. Next Sarah finds herself on the shores of Kingsmouth, a forgotten fishing town which holds an incredible secret. A would-be messenger reveals the sad truth: he and the rest of the town’s denizens are suffering from a curse that is gradually turning them into ghoulish, mutated ocean creatures… a curse that was cast by none other than the mayor, Murray, and the old sea-devil himself, Davy Jones.
