Documentary in which Joanna Lumley crosses three continents in search of the truth behind the story of Noah's Ark. Was it a fable? Was there really a flood, and who was Noah? This is a journey where myth, legend, religion and science all play their part and Joanna soon discovers that the story is much older than she first thought. Her detective work takes many twist and turns, from the nomadic traditions of Mount Ararat in Turkey to tales of ancient Sumerian floods thousands of years ago. The adventure continues in India as a Hindu temple holds clues to a long forgotten ancient civilization. But it is on Jebel Shams in Oman, the highest mountain in Arabia, where the story actually comes together.
