National Geographic Archeologist Dr. Thomas St. John resurrects the investigation of the 1860 sunken slave ship, Claudia, in search of generational annulets that are recorded to have elements of supernatural powers and great wealth.  The four annulets: Earth, Wind, Fire, and Water, are connected by ancestry, which was lost at sea when two hundred slaves were drowned in a shipwreck over 160 years ago.  Dr. Thomas St. John is aware that anyone outside of the descendants who seeks possession of these annulets can result in deadly consequences. Instead, he devises a deceptive plan with his partner, Lady Isis Jones, by convincing fourth and fifth-generation descendants to join them in a friendly voyager to recover the annulets in the Atlantic Ocean. To their surprise, their plan takes a deadly turn.
