Pepe Lange goes swimming in the Kiel Fjord every day. When temperatures allow, he goes snorkeling. He explores the underwater world and collects trash. The short film follows him on his special patrol. This gives viewers a glimpse into a mysterious world that normally remains hidden from most of us. When we walk along the Kiel Fjord, we can see the fjord, but not quite into it. We can only guess what it looks like below the surface. That's why filmmaker Sven Bohde and his team want to offer the opportunity to look beneath the surface and experience what it's like down there together with Pepe Lange.
