The first episode takes us from Denmark, via the Darss Peninsula in Germany and Lithuania’s Curonian Spit to Latvia. In June, hundreds of seals gather on the island of Anholt. In the autumn of 2015, an absolute rarity appeared: a Sowerby’s beaked whale. The Darss Peninsula attracts thousands of cranes in the autumn. The Curonian Spit is home to many sea eagles. We end along Latvia’s primal coast. The biggest seal in the Baltic Sea, the grey seal, lives here.

The second episode presents a world of thousands of islands between Estonia, Gotland in Sweden and Finland. In the autumn, the mating calls of the moose can be heard everywhere. The largest gathering of grey seals in the Baltic Sea can be found in the Bay of Riga. On Gotland, golden eagles breed in trees. Close by is the biggest guillemot colony. In June, the young jump from the cliffs in their hundreds. 300 kilometres further north is Finland’s archipelago. Home to brown bears.

The third episode takes us to the Bay of Bothnia. In winter, home to the ringed seal. More than 10.000 of the animals still live here. 300 kilometres further south millions of fish head for the coast. Giant pikes fight their way through the water to lay their eggs. The Kvarken Archipelago is also the habitat of the flying squirrel. In the spring, males begin looking for females. For the same reason brown bears roam through the Skuleskogen National Park on the other side of the bay.
