Claudia Gawinski reports missing her adult son, Daniel Gawinski, since he returned home from Australia and had an appointment to buy a dream car in Wismar from Kilian Klein, who claims never to have met Daniel. Klein's wife Susanne believes she saw him fight an unidentified adult man, nowhere to be found. The team is startled to find unusual links. Kilian Klein was cleared in court years ago for another murder in Hamburg, which DNA now proves he committed, but a second trial would be illegal. After Daniel's father Norbert Siegmann turns up, hidden identities prove crucial, but the story gets even more macabre.
