In Mexico, Nick travels from Los Mochis in Sinaloa to Creel in Chihuahua, witnessing astonishing feats of railway engineering and breathtaking landscapes.

Travelling north from Trondheim, Nick stays for a night on the River Namsen, takes a helicopter ride, meets a reindeer herder and goes swimming in near freezing sea.

From the misty mountains of Sa Pa to the jamppacked city of Hanoi with its five million scooters, Nick discovers a Vietnam of newfound prosperity that is developing fast and thriving.

Over the course of three train journeys, Nick visits Malaysia, a country of contrasts. It is a land of advanced technology, rural simplicity, megacities, virgin rainforest and many different cultures.

Nick's journey begins at dawn in snowy Anchorage and takes in the Matanuska Glacier.
