The North Sea and the Baltic Sea seem familiar to us. And yet they have by no means revealed all their secrets. The four-part documentary series shows up close the dramas that take place between the fauna and flora in the depths of the seas: Killer whales chase grey seals and a small catshark encounters its worst enemy. Seahorses perform their graceful wedding dance and bull seals fight for supremacy on the beach. But the documentary series shows not only the splendor, but also their vulnerability.
