Maritime mysteries -- old and new -- come to life in this 10-episode series, 
combining scientific data and digital re-creations to reveal shipwrecks, 
treasures, and sunken cities on the bottom of lakes, seas and oceans around 
the world. 
Innovative technology allows viewers to see what lies on the floors of large 
bodies of water such as the Gulf of Mexico, the Nile, the Indian Ocean, the 
Baltic Sea and the Atlantic Ocean as if they had been drained. 
Then, in a quest to explain natural wonders and man-made catastrophes, stories 
tell of how vessels sank, what ancient geological formations reveal about life 
on Earth, where Nazi secrets now reside, and why so many continue to search for 
the legendary city of Atlantis
