'Echos' Answers Booming Demand for Authentic International Series at Berlinale Lise Pedersen, provided by FacebookTwitterEmail A hallmark of Germany’s flourishing TV production industry, drama series “Echos” was unveiled at the Berlinale’s newly established Series Market Selects label this week. A coming-of-age show of six one-hour episodes, “Echos” tells the story of Max, Nellie and Janosch, three privileged twenty-somethings from Munich. Always in search of new thrills, they head to an illegal rave party in the Munich catacombs. But things turn horribly wrong when a fire breaks out and some of the ravers go missing, including Nellie’s brother, Max. Nellie and Janosch gradually uncover an invisible web that spins together the story’s different characters, from a real estate tycoon to the investigating police inspector and the shadowy figures living in the bowels of the rich Bavarian city.
