The film portrays a case in which millions of euros of damage were caused by insufficient compliance with the fire protection regulations for welding work. It was not just Erbsand, the locksmith, who took the job of a welder and carried out welding work, although he had never acquired a certificate.

Dombrowsky, the accountant of a medium-sized state-owned company, is at the center of the action. Driven by petty-bourgeois addiction and enrichment addiction, he uses shortcomings in the operational management and accounting system to take control of public property.

He succeeds in including the young, inexperienced production manager Pause in the manipulation to cover up the planned arrears.

According to Anglo-Saxon law, in the event of an unnatural death, an inquest takes place, a kind of public preliminary investigation into the cause of death. An unnatural death can turn out to be an accident, suicide or murder (or killing by someone else's hand). Unionist Paul Anders asked the same question as Inquestor: accident, suicide or murder? The death of Ms. Gast is examined under these three aspects, and soon the medical-criminalist question must expand to a socio-political one. Ms. Gast died at the age of 27 four days ago.

Frank Seeburg (Stanislaw Zaczyk), a successful writer, is called to the bedside of his former schoolmate, journalist Volker Rochmann (Horst Drinda), in one night. He was seriously injured in an accident on the highway and hands his old friend a key to a locker in which Rochmann's notes are found. Seeburg is shocked because Rossmann worked on the investigation of three murders disguised as suicide. Is there a connection between the three murders and was his serious accident possibly an attack on him?
