The body of Lilli Fennrich is found in the countryside outside the city of Wiesbaden. Her husband Jasper has already confessed to the murder and is in pre-trial custody. A seemingly easy case awaits Police Inspector Winnie Heller, who was transferred from Cologne back to her hometown of Wiesbaden. The transfer allows her to not only reorient her professional career, but it also gives her the opportunity to be close to her sister Elli, who is in a coma since she was in a car accident.
