The Baltic Sea is dying. The herring is poisoned. The cod has become dwarf. We are swimming in a nasty goo of algae.  Is it too late to save the sea for our grandchildren? With the most advanced UV technology, and some of the Baltic’s most experienced diving cameramen, we investigate the state of the ocean in depth. We meet its inhabitants, from plankton and jellyfish to cod and seal.

The sea is dying, not dead. In the darkest holes in the Baltic Sea we find hope, a secret, a treasure. It’s a promise that the immense power of nature can overcome man’s senselessness.
