Treasure Quest - Season 1, Episode 09: The Liberty Ship

Odyssey Marine Exploration, a world leader in private deepwater exploration and recovery, is gearing up for its most ambitious season of treasure hunting yet. Its goal for the 2008 season is extraordinary: to find and recover two of the greatest shipwreck treasures ever lost at sea. Their value: well in excess of one billion dollars. Yet the stakes of this adventure aren't limited to riches. Odyssey Marine Exploration is setting itself another challenge: to penetrate the mysteries of dozens of never-before-seen shipwrecks -- and to bring to light their stories of untold riches, courageous men and women, tragic endings, and remarkable rescues.
