In their first case, the Dresden detectives Karin Gorniak and Henni Sieland are confronted with a brutal murder. The hit world is in turmoil. One of the local heroes, Toni Derlinger from the singing duo "Toni & Tina", was found dead in the wings during rehearsals for the entertainment show "Here Plays the Music". The investigators have the stage blocked and get an overview of the personal environment of the dead man. At first glance, Toni was popular with everyone and had no enemies. His wife and singing partner Tina is in despair, and longtime manager Rollo looks as if he has lost a son. It's hard to imagine a gruesome murder in this environment, which many fans appreciate as the last bastion of an ideal world.
Was it a disappointed fan who felt rejected? Or was it about money? Apparently things weren't going well for Tina and Toni lately, the two were clearly on the decline. The offspring in the Schlager business pushes relentlessly, folk music continues to develop. Maik Pschorrek, a slick young manager and concert promoter, is conquering the market with dubious methods and has signed up-and-coming stars such as the trendy Laura and the popular rock'n'rollers "Herzensbrecher".
Did Toni want to switch to Maik Pschorrek shortly before his death to revitalize his career? Couldn't Rollo face the fact that his artists, whom he had once brought together and built up over many years, are leaving him? When the murder weapon with Rollo's fingerprints is found, everything points in the direction of the lonely manager. While the investigators Henni Sieland and Karin Gorniak penetrate deeper and deeper into this world of reality and appearance, their colleague Maria Mohr, a young police officer, discovers the crucial clue and puts herself in great danger. In addition to the case, Karin Gorniak also has to deal privately with the issue of violence. Her son Aaron wrote a corresponding rap text. His class teacher, Ms. Schwarz, thinks that Karin, who is a single parent, is overwhelmed and that the teacher is hysterical.
Karin's attempts to spend more time with Aaron fail miserably. Her colleague Henni Sieland, on the other hand, would like nothing more than to have a child with her boyfriend Ole, who, however, often behaves like a child himself. The first "crime scene" with the new team from Dresden.
