The charred body of a woman presents a huge challenge for forensic medical experts Dr. Robert Kolmaar and Dr. Judith Sommer, who can’t offer much immediate assistance to CID Inspector Jockel Löw. There is nothing that can provide any clues to the origin or identity of the dead woman. Using a computer simulation, Dr. Robert Kolmaar reconstructs the appearance of the deceased, hoping that when this information is made available over the media it will strike a chord with somebody in the general public. Our experts are stunned, however, by the response - when a woman suddenly appears in front of them who could be the twin sister of the victim! The beautiful Julia Wander may well now be in danger herself, though, since it could be that the murderer made a mistake and will come back for her. Sure enough, not long afterwards Julia is attacked in her apartment. But when Inspector Löw makes some enquiries from the Wanders’ family doctor, a secret from the past comes to light which provides a most unexpected twist to this case...
