After four years in prison for the manslaughter of her father, Sara Manzer wants to look ahead. She has support for her new life - primarily from her friend Marlene, who takes her into her apartment. Sara, who has turned from a party girl into a reserved woman as a result of her imprisonment, wants to shake off memories and reorient herself. But then the police show up at her door. A former colleague was stabbed and old files of her case were found on him. She reluctantly admits that she spoke to Benno Rose before his death. He had new insights into her old case that should relieve her. Sara insists she had nothing to do with Rose's death. Which doesn't stop the inspectors from investigating.
