Travel is Joanna Lumley's passion. She has travelled the world for ITV, thousands of miles that take weeks to shoot and months to edit. Inevitably, she has never been able to show us everything – but now she is revealing unseen stories and special moments of how these journeys are made, and why she loves making them. In this last episode, we find Joanna in Iran exploring the tomb of Cyrus the Great before following the Silk Road through Azerbaijan, Georgia and onto Venice. Then off to Haiti and Cuba for some unseen adventures in the Caribbean.
