Plot synopsis: A journey along Europe’s most spectacular night train routes, uncovering hidden natural stories along the way — stories of landscapes, wildlife, and the ecosystems that shape them.We meet people on board and along the routes. What unites them is a special connection to nature. Traveling through the night and into the early hours of morning, our routes take us across Germany, Scandinavia, Hungary, Austria, Switzerland, and almost the entire Balkan Peninsula, all the way to the outskirts of Istanbul.
