The children think she just fell asleep, but Marlene, their teacher, is dead. The tests in the clinic show that she is brain dead. Marlene's parents can't accept that it's the same thing. Not what her daughter wanted in this case either. Dr. Ballouz, who faced the exact same decision of whether or not to donate a loved one's organs when Mara died, relives his trauma a second time. In order to get her husband Norbert, who was stubborn with age and, in her opinion, no longer fit to drive, out of the road, Eva Willeke swallowed his car keys. But Norbert has driven a car all his life and has no plans to stop. Now he demands his car keys back and brings Dr. Mark Schilling and Dr. Barbara Forster at the edge of her patience.
