Jana Friedrich is a young, dedicated doctor from the provinces who is completing her specialist training as a forensic pathologist when she is offered an internship at a renowned Hamburg institute of forensic medicine. A dream comes true for her. An internship with her great role model Kurt Bremer, a luminary in his field. Jana has read all his books. She knows that working in this field is not an ongoing murder mystery. But she is shocked when she is confronted with various cases of abused children instead of exciting criminal cases. Jana soon experiences first-hand how difficult it is to bring those responsible to justice and to remove the children from their tormentors. When she and her mentor even fail in court, despite the death of an infant, she decides to take a more active role and get involved.
