Tatort S2010E27 - Borowski - 15 - Borowski und eine Frage von reinem Geschmack

15-year-old Florian dies of an allergic shock after drinking the energy drink "Vitanale". Investigations reveal that the fitness drink was overdosed with food coloring. Is that the reason the boy died? It quickly becomes clear that although the boy was allergic, the fatal amount was anything but a coincidence. A first hot lead leads Borowski directly to the Kallberg dairy, which aggressively markets its top product "Vitanale". A break-in at the dairy seems to prove that sabotage is involved. A young environmental activist who has been running a campaign against "Vitanale" for some time and does not shy away from dubious methods initially becomes the focus of the investigations .
But the ambitious company boss Liane Kallberg and her quarreling family also seem dubious to Borowski. Sarah Brandt, who comes into contact with Borowski rather involuntarily, proves to be a helpful informant about the Kallbergs. When a blackmailer reports, events begin to unfold. It soon becomes clear that behind the crime lies a human drama in which the dead boy's father plays a key role.
