Casstorff - 15 - Und Tschüss

Arno Dahm, entrepreneur of a company with fair trade products, dies trying to kidnap him. The perpetrators are able to flee – only 13-year-old Doro witnesses the crime – but reveals herself to no one. The investigative work begins: Casstorff is irritated that his girlfriend Wanda Wilhelmi is not there. When the prosecutor heard the dead man's name on the phone, she wanted to go to the scene of the crime immediately. In the meantime, Holicek examines the professional environment of the dead man and is the first to meet Karl Dursthoff, chairman of the export association, who knows about disputes between the dead man and his partner Müller.
In fact, Jannik Müller, co-owner of thecompany "Fair Global", understand that it was not easy with Dahm - after all, Dahm's high moral standards in everyday business stood in their way. Wanda Wilhelmi still does not appear and not only Casstorff is alarmed: The LKA sets up the special commission "Wanda" - assuming that the public prosecutor was kidnapped on purpose. Also on board is Jenny Graf – Casstorff's former employee who now works for the LKA. Together they examine the cases that Wilhelmi was working on before she disappeared and try to find out what the connection between Dahm's death and the kidnapping of a prosecutor could be.
