More than 2,000 years ago, Greek and Roman galleys sailed the Mediterranean Sea loaded with goods for trade or soldiers for conquest. Today, off the coasts of Italy, Spain, and France, hundreds of these ancient shipwrecks, sunk for centuries, are being pirated by clandestine salvagers and deep-sea divers. In the past twenty years in France alone almost 400 shipwrecks from the Greek and Roman eras have been found. All but three had been pillaged before being discovered by the authorities.

This films narrates the piracy of amphorae and other artefacts from the sunken Roman ships off the coast of southern France and the measures being taken by UNESCO for the protection of underwater heritage
