Novel apprentice Annemarie Kleinert is shortly hospitalized after a fire at one of the cheap barbershops run as a chain by Gregor Krantz, who exploits un(der)qualified staff, promising them a 'training' without value, and may be practicing insurance fraud as he's in debt. His rival Leo Faber can't compete with those dumping prices, despite superior quality and innovation, like the new die developed by his pet apprentice Micha. Motives and opportunities abound, but another crime exposes the truth bluntly. Claudia's adult son Max Fischer visits fro the weekend and treats the precinct to his handyman skills, well beyond Wolle's.
