One morning, Gerd Vogt and his five-year-old son Noah disappeared without a trace from their single-family home in a new housing estate in Breisgau. A large amount of blood in the bedroom indicates a possible crime. Possibly a knee-jerk action by the depressive father? Gerd's wife Sandra was allegedly not at home that night. But because of her odd behavior and because of the contradictory statements about the Vogts' marriage, she appears in a dubious light. It is clear that Sandra is hiding a lot from Franziska Tobler and Friedemann Berg. But whether that's relevant to the case or not is something the inspectors have yet to find out. Because Sandra Vogt doesn't reveal anything, not even when she becomes the main suspect in a murder case.
