Wenn Wattwürmer weinen

On a beautiful summer day, the marketing manager from Neuharlingersiel is found lifeless in a beach chair. The cause of death: poisoned red wine. The criminal police focus on the deceased's female acquaintances – and have their hands full. Teacher Rosa, who usually doesn't miss a new case, is surprisingly reserved, as her private life keeps her busy. However, when another man dies and the same poison is found in his system, her curiosity is piqued. Between a hair salon, beekeeping course, and a sea burial, the cult trio of Rosa, village policeman Rudi, and postman Henner once again looks beyond the obvious – and discovers astonishing things.
