In a room with no windows on the eastern coast of Africa, an Englishman, James Moore, is held captive by jihadist fighters. Thousands of miles away on the Greenland Sea, Danielle Flinders prepares to dive in a submersive to the ocean floor. In their confines they are drawn back to the Christmas of the previous year, where a chance encounter on a beach in France led to an intense and enduring romance.
James and Danielle meet on vacation and fall in love. She's going to the dark North Atlantic bottom to find life. He's going to Somalia to find a terrorist but gets a dark cell.
