Trevor McDonald is aboard the luxury yacht Christina O, formerly owned by Aristotle Onassis.

Sir Trevor visits three countries where the landscape has determined how people live there, whether it is living by an ancient lagoon in Santorini, being a cowboy in southern France or turning a barren Tunisian landscape into a multi-million dollar Hollywood film set.

Trevor visits Vesuvius on the west coast of Italy and meets a Naples prosecutor responsible for dealing with members of the mafia.

Trevor pays a visit to Egypt and the resting place of Cleopatra's palace, in the harbor of Alexandria.
