Mountain climbing is currently Britain's fastest growing sport. However, with the increase in popularity comes an increase in the number of people who need to be rescued. This past winter 64 people were caught in Scottish avalanches and ten of them died as a result. Tonight's programme features unprecedented access to the organisations that make up the Scottish Mountain Rescue, which include 25 civilian units, two teams from the RAF and helicopters from both the navy and the air force, as they attempt to battle against the elements to rescue injured climbers.
