Chief Inspector Ehrlicher is just about to leave for his vacation in Paris when his boss sends him to the new Central Stadium in Leipzig, which is scheduled to open in two days with a big celebration. There, Susanne Fellner, Head of Human Resources, was found dead. Ehrlicher drives directly from the airport to the stadium, where his colleague Kain and the forensics team have already started their work. During the investigation, the police officers first come across dissatisfied employees. The young HR manager had made herself unpopular because she was only interested in her own career and profitable figures. So she recently fired the employee Ralf Rogge. Caretaker Georg Bracht should also be fired.
Bracht has been toiling here for 40 years and knows the stadium boss Hartmut Utz from the time when he played football successfully himself. Bracht is proud that his son Daniel made it as an engineer to become the technical manager in the company. So could the murder be an act of revenge? Anna Fellner, the sister of the murdered woman, confirms that Ralf Rogge threatened Susanne. The convicted ex-boxer had renovated Anna's dance studio, but then couldn't agree on the price with Susanne - and freaked out. Ehrlicher and Kain prick up their ears when they learn that stadium manager Utz personally informed Anna Fellner about Susanne's death. It is also strange that Utz avoids a conversation with the commissioners. The commissioners seem to be on the right track.
As it turns out, Utz had an affair with the murdered woman. Then Ralf Rogge demolished Anna's dance studio. When he is arrested, he confirms the row with Susanne, but protests his innocence in her murder. In the middle of the devastated rooms, Cain finds a bill that Susanne had apparently hidden there. The trail leads to Hannelore Utz, the stadium director's wife, and her shady dealings. Was she blackmailed by the dead?
