He secretly watched them, filmed them, even when they were sleeping. Now he's asking for three million. For not killing them, the children of the successful pharmaceutical manager Eva Steiner (Nina Kunzendorf). Eva Steiner turns on the police and Inspector Lucas (Ulrike Kriener) takes over. There are still four hours until the money is handed over. Not enough time to prepare everything in detail, Lucas has to improvise. The transfer of money turns into a fiasco. Eva Steiner and the blackmailer, Dr. Robert Dohnen (Ben Braun) get into a shootout and collapse badly injured. Dohnen is Eva Steiner's brother-in-law, and until three months ago he was also her most important employee: head of the research department. The motive for the blackmail seems clear: revenge for the unintentional release shortly before the conclusion of amillion deals.
With her new employees, Commissioners Alex Eggert (Anna Brüggemann) and Tom Brauer (Lasse Myhr), Commissioner Lucas sets out to work through the failure and comes across a number of inconsistencies. What is the real reason for Dohnen's dismissal? What role does the multi-billion dollar merger of Eva Steiner's company with a Swiss pharmaceutical company play? And where did the weapon come from that injured Dohnen and Eva Steiner? When the inspectors discover a connection between the extortion and the murder of a petty criminal, Lucas has to investigate whether the mastermind behind the events, the real culprit, is not to be found in his own ranks. This is also supported by the fact that viral bullying and defamation are spreading within the team.
