The story of an unlikely passion in a place that a large part of the world only knows as Oktoberfest City: Munich has become the home of a surfing crowd of urban individualists who pursue their dream by riding a river wave far from the ocean. "Keep Surfing" portrays six surfers of the Eisbach hardcore: Dieter, who was among the first to discover river surfing in the late 60s and still rides the waves every day with his two grown daughters. Walter, a working-class philosopher who now lives as a kind of lone wolf in Sardinia, where he rides his own wave every day. Golden boy Quirin, who has become a surf pro and global nomad – even though his heart still beats for Munich, where everything started. Among those who joined the local community is surf punk Eli Mack, for whom river surfing is a way back to the roots of surfing. And surf legends like Kelly Slater, Ross Clark Jones, and Taylor Knox have tried their luck on the Munich river wave.
