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 investigation: the traces in the house were manipulated, the break-in was apparently faked - forensics finds older traces of blood... Neighbors and colleagues give different accounts, but there are indications that Fischer beat and terrorized his wife. Did he want to prevent her from leaving him, did he kill her and fake a kidnapping? Or did Kathrin Fischer secretly prepare the escape and stage the bloody act to incriminate her husband, because she can only be safe from him if he is in prison?
