Bettany uncovers a society which grew rich by selling copper, and visits the crowning glory of Bronze Age Oman: mysterious 5000-year-old beehive-shaped tombs. She also discovers an ancient irrigation system that forged the country's culture and civilisation over the last millennium, and finds out how frankincense, once one of the most sought-after products on the planet, is still harvested by tribal families today.
