The 5th case for the East Frisian investigator team Femke Folkmer and Tjark Wolf: Sven Koch captivates with a tale of revenge surrounding the collective guilt of a village community on the East Frisian North Sea coast, addressing xenophobia and the personal secrets of seemingly well-known individuals. A criminal case set against the backdrop of German contemporary history following the fall of the Iron Curtain, and of course, with the magnificent North Sea coastline as a backdrop. A horse ripper is on the loose in Werlesiel, the small fishing and tourist town on the East Frisian North Sea coast. When people also start to die, it becomes clear that the villagers are hiding a terrible secret. A secret that the LKA special department SKO, led by Tjark Wolf and Femke Folkmer, must uncover. The events lead back to the time when the Iron Curtain fell and – as is the case again today – refugees came to Germany.
