Kate begins her epic journey following high in the hills of southern Oman. With her own supply of the precious resin, she walks with the Al Mahri tribe - the descendants of the ancient traders - and their 300 camels along the original trail through the scorching Empty Quarter desert. Crossing into Yemen, Kate arrives at the world's first skyscraper city, where her frankincense is used at the ritual blessing of a newborn baby. From the modern frankincense trade capital of Aden to an incredible camel-jumping contest, Kate journeys north and enters the mysterious Kingdom of Saudi Arabia.
