Caught up by the past, Chief Inspector Anna Janneke (Margarita Broich) reaches her limits. The convicted murderer Alexander Nolte (Nicholas Ofzcarek) is on the loose again and tries to contact her. During her time as a police psychologist, she prepared the report that brought Nolte to life imprisonment. After almost 20 years he has served his sentence, was released and now works in the dental laboratory of Roland Burmeister (Sabin Tambrea). Alexander Nolte is looked after by the psychologist Helene Kaufmann (Ursina Lardi). The homeless man Martin Busche (Manuel Harder) is found stabbed to death in a driveway. This murder remains a mystery to the two Frankfurt inspectors Paul Brix (Wolfram Koch) and Anna Janneke.

The situation becomes dramatic when he ambushes her at home and her terrible suspicions are confirmed. In the new case of Janneke and Brix, truth and seduction lie side by side. Third case of the Frankfurt investigative team Anna Janneke (Margarita Broich) and Paul Brix (Wolfram Koch).
