Summary [PART 1] Rescuing Pia Hoefling, under whom a metal cables bridge semi-collapses, Tobias and Toni get in trouble themselves as more cables snap, clearly due to sabotage, so they must call for 'resigned' Markus to rescue them from Michael's helicopter. Twelve year-old Florian Meixner's ever-bickering separated parents Lorenz and Lisa start worrying as he fails to return from a mountain walk with his loner grandpa Rupert, having taken a longer route due to the unready bridge and call the rescue team. Rupert needs his medication daily, but has none left, finds out that Florian sabotaged the bridge to avoid returning home and exerts himself even more excessively when the doted knave falls down, needing to be pulled up with Rupert's last strength.
