Alexander Bukow is a veteran cop who doesn't mind working at the edge of the law to get results. Bukow knows the town of Rostock, like his own backyard and he should; it's where he grew up. He has contacts on every corner and can be charming enough to wrap friends and enemies around his finger. Katrin Konig has a sterling reputation as an analyst and profiler and is esteemed by all who know her for her assessments and professionalism. For Konig, the job is her life, which is how she became such an accomplished criminal profiler. She's a strait-laced control freak and all too aware of her partner's seedy past and questionable allegiances. Despite, or perhaps because of their differences, they make a successful crime-fighting team; when they're not fighting each other.
