Jacques Cousteau and the Calypso crew journey across two seas - mediterrean and Caribbean - to recover the remains of great ships. Off northern Crete they find skulls, scattered bones and round pellets of grape-shot fired in a 300-year-old battle and at another site, 1st-century Roman jars. Their biggest wreck is uncovered at Martinique. In 1902, 30,000 people died when Mount Pele erupted and a harbor of ships disappeared into the depths. But at 150 feet, Cousteau's divers sight the Roraima - broken in two but intact.
