A wife initially disappears without a trace from her house, which was obviously broken into. Traces of blood suggest the worst. Her husband Simon Fischer called the police, but then left the house. Gorniak, Winkler and Schnabel initiate a large-scale search for Kathrin Fischer. The desperate Fischer himself quickly becomes the focus of the investigations: the traces in the house were manipulated, apparently the break-in was faked - but the forensic technicians found older blood residue... Neighbors and colleagues give different statements, but there are indications that Fischer beat his wife and terrorized.
Did he want to prevent her from leaving him, killed her and faked a kidnapping? Or did Kathrin Fischer secretly prepare the escape and stage the bloody deed to incriminate her husband because she can only be safe from him when he is in prison? Her friend Beate Lindweg plays a dubious role in this marriage: Before Kathrin, she was in a relationship with Simon Fischer... The Dresden investigators have to find out what happened and descend into the abyss of a toxic marriage.
