Zermatt to Geneva

Armed with his 1913 railway guide, Michael Portillo travels from the Swiss Alps to the shores of Lake Geneva. Along the way, he is caught up in a war zone with the Red Cross and rescued from an avalanche by a St Bernard puppy. He takes to the skies in a vintage bi-plane to retrace the epic journey of the pioneering pilot who was first to fly over the Alps and tries his hand at watchmaking, James Bond style.
