The historian and classicist explores Greece from the time of the Ancients up to the present day. She begins by exploring a graveyard of ancient shipwrecks in the waters of the Eastern Mediterranean, then enjoys the tradition of a warm welcome on the island of Chios. Next, Bettany heads to the island of Lesbos, visiting the ancient Greek Theatre of Mytilene and taking a dip in the island's thermal waters. Finally, Bettany stops on Samos, an island known for both its ancient naval power and its famous sixth-century BC resident, mathematician and philosopher - Pythagoras.

The historian and classicist goes Greek island-hopping to explore their history from the time of the Ancients to the present day. In Santorini, she visits a Minoan city preserved in time by one of the most violent volcanic eruptions in history. Bettany's next port of call is Naxos, where in an abandoned marble quarry, she finds a genuinely monumental statue of the god that has lain there for thousands of years, before heading to a taverna to take part in some local festivities. The presenter later arrives in Sifnos, where long-distance communications were mastered millennia before telegrams or telephones.
