While James More is held captive by terrorists in Somalia, thousands of miles away on the Greenland Sea, his lover Danny Flinders prepares to dive herself in a submersible into the deep bottom of the ocean, tormented by the memories of their brief encounter in France and her inability to know his whereabouts.
The OSSA discovers a spacecraft thought to be at least 300 years old at the bottom of the ocean. Immediately following the discovery, they decide to send a team down to the depths of the ocean to study the space craft. They are the best of best, smart and logical, and the perfect choice to learn more about the spacecraft.
