An anonymous call announces a car booth bomb at Bochum precinct. Heldt spots and stop just in time the suspect car and presumed perpetrator, chemist Derja Afridi, an Afghan Taliban-widowed refugee employed by paint firm Kraft Farben. It's a fake, possibly a ploy to shut up Derja, whose uncooperative supervisor Luca Wollenhagen and devoted management secretary Luise Krugkamp consider her a threat to the company reputation as toxic product whistle blower. Heldt poses as dirty cab form owner to dubious local reporter Thorsten Geilandt and illegally uses Achmed's hacker talent. State attorney Ellen, already uneasy about their illicit affair, turns on Niklas, who grills the family management.
