Following Landstück (2016), Volker Koepp's documentary Seestück is about the magical, natural setting of the Baltic Sea, its coasts and its people – including fishermen, seamen, scientists and young people on both the Baltic and Scandinavian shores. Conversations meander from Caspar David Friedrich to Copernicus, Rousseau and Kant, or simply life itself. Present concerns address the sea's threatened ecosystem and political frictions among the neighbouring countries. One universal truth applies for the small Baltic Sea too: The landscape is a window to the world.
