The prosecutor has the floor

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. Master Hobohm, who was otherwise known to be extremely conscientious, has to answer for himself in court because he not only trusted the pretended welder but also neglected his supervisory duties.
