Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!

Follow a three-month-old baby whale on a magical journey down one of the Earth’s great ocean highways to discover the incredible world of ocean currents. She will never know it, but as she swims with the flow of the current, her story becomes inexorably connected to our own. Ocean currents are hidden marine rivers that flow around the Earth. They are responsible for the fish we eat, the rain that feeds our crops, the snow that covers our mountains - even the air we breathe, and they have been helping to keep the temperature of our planet just right for life for millions of years. As our young whale goes with the flow of the current on a great migration from the warm tropics to the frozen ice floes of Antarctica, she meets the curious creatures that call the current home.

Bacteria, viruses, but also fungi, algae, pollen, and even insects: micro-organisms thrive and circulate constantly in our sky. How can so many living beings find their way into the air and circulate? How do they survive? And what influence do they have on our lives and the living world? Biodiversity, health, climate: it is only recently that scientists have begun to understand how this discreet aerial "plankton" affects our lives and our ecosystem. But despite their many virtues, some of these micro-organisms are now threatened by human activities. With the help of experts and 3D models, this scientific investigation plunges us into the heart of a still mysterious world, and reveals the diversity and fragility of the air we breathe.
