When winter falls each year, millions of people flock to the Alps. However, the increasing shortage of snow is becoming a serious problem for many ski resorts. This documentary looks at the various aspects of this shortage and the main problems it causes. It is a winter journey through the Alps in the company of a large group of people who live on tourism; their business and income depend on snow. They are, however, small cogs in a much bigger system, the winter tourist industry, which is developing at increasingly dizzying speeds.
