Legend has it that thousands of years ago, the island of Atlantis once housed an advanced civilization - which. then vanished completely in a violent cataclysm. Merely a myth? Or did Atlantis really exist? In an engrossing journey back to the ancient world, Jacques Cousteau and crew travel to the islands near Greece to see whether there was a connection between the violent earthquakes that racked the region and the fall of the gracious Minoan civilization that flourished on Crete during the Bronze Age. Could the Minoan civilization indeed have been the basis for the Altantis legend? Cousteau also examines the roots of Plato's account of Atlantis. Was it a folk memory passed through generations or Plato's own views on war and corruption?
