Anna von Boetticher, Germany’s most successful freediver, is passionate about water in all its forms – from deep and murky to crystal-clear, from tropically warm to frozen. Even as a child, she realised she could dive for longer than most other people. Her boundless curiosity drives her ever further, in search of adventure even in the most unusual and remote places. In this film, she dives into local waters – from the Schlei to the Upper Rhine.
