"Schieren auf allen Kanälen" - "Die Nordreportage" accompanies the "Fleetenkiekers" before, during and after their hardest assignment of the year: On the first weekend in July, the world's largest triathlon is scheduled to take place in Hamburg and around 10,000 athletes plunge into the Inner Alster for this. Therefore, it is important for organisers and athletes that the event runs smoothly - and that there is no rubbish. Armed with a route map and a landing net, the volunteer garbage patrol starts their most important mission of the season in morning grey, an intensive race against the clock begins. 48 hours - an exciting hero's journey with a sudorific, Hanseatic and ecological challenge.
