The Cairngorms is Britain's largest and wildest National Park. A land of Arctic extremes in the heart of the Scottish highlands. Its granite mountains and ancient pine forests are home to some of our rarest and most spectacular animals, including golden eagles, ptarmigan, capercaillie, red deer and crested tits. This lyrical and thought-provoking film reveals the inner secrets of this wild landscape over a year through the eyes of individuals who know and love the Cairngorms: a mountain guide, an artist, a salmon ghillie, a gamekeeper and a nature writer.
