"I'm embarking on a 7000-mile journey following the route of the legendary Silk Road, that throughout history helped spread all manner of foods, inventions and cultures across Asia and Europe...my most adventurous and exotic journey yet." Joanna Lumley.

This epic new four-part series is Joanna Lumley's grandest and most challenging journey so far, a breath-taking odyssey from Venice to the Chinese border along the veins of the ancient Silk Road.

A perilous network of paths, the Silk Road shaped the modern world, bringing silk, printing, spices, gunpowder, and many other things to the West. Joanna's adventure will see her travel through a breath-taking array of fabulous landscapes as she crosses continents, deserts, mountains and steppes, boldly following in the footsteps of the merchants, conquerors, kings and pilgrims who once lived and died along this route.
