During a firefighting operation, Pascal suffers from dangerous smoke poisoning. Jules, who is already constantly worried about his father, wants to get to the bottom of the cause. Did someone neglect the maintenance of the breathing apparatus? Or is this possibly sabotage and a targeted attack on the fire department? Taara is skeptical and thinks Jules is just in panic mode again. Only Malin understands his fears and actively supports the investigation. A spontaneous declaration of love ensues – or is Jules on the wrong track here, too?
