Filmmakers Almut and Christoph Hauschild travel along the Baltic Seas, observing its many surprises. Their journey spans from Anholt, home of the largest seal colony in the area to Latvia's coast, where a sunken trawler is a meeting point for grey seals. Witness baby seals learning to swim, peregrine falcons feeding their young, red deer quarreling, and more in this first episode of the three-part series.
