Norway's fjords are a little-known wilderness. Billions of herring darken the waters and orcas feast on the banquet. Salmon leap up waterfalls and colourful sea slugs glow in the deep. Diving below the surface, award-winning filmmaker Jan Haft reveals the extraordinary diversity of life hidden within the deep waters. It's an intimate portrait of a unique landscape - in the dark, icy grip of winter, under the magical glow of the northern lights, and during the long polar nights of the midnight sun.
