Central Europe’s largest tributary of the Danube, the 323-mile Inn River flows through Switzerland, the Austrian Tyrol and Bavaria. Through the ages, the Inn’s legendary natural beauty has generated unique cultural regions. Called the green river from the Alps, the Inn has many faces: picturesque sandy islets, extensive wetlands, riparian forests and gravel banks. The source of the Inn lies in the Engadin Valley, in the Swiss canton of Graubünden, a famously gorgeous landscape with local populations of ibex and ptarmigans. In Tyrol and Bavaria, where the river finally empties into the Danube, beavers and European otters take advantage of the Inn as a habitat. The film also addresses the serious threats the river faces today: signs of massive human intervention are clearly apparent all along the Inn’s course, with consequences suffered by animal and plant life alike.
