Secrets (2013)

Season 6: Episode 4

Ancient records marked a modest Tunisian coastal town as the location of a one-time thriving Roman metropolis called Neapolis, but for centuries there was little archaeological evidence to support such a claim. That all changed when a massive storm exposed the ruins of ancient streets and buildings beneath in the Mediterranean Sea. Join a team of scientists as they investigate the submerged city in hopes of revealing new secrets about the rise and fall of the world's greatest empire.
