A model family's happy life unexpectedly goes off the rails when the carefree Hedi, played by Laura Tonke, suddenly starts having panic attacks. First mental illness and then drug dependency – the happiness that these happy-go-lucky thirty-somethings once took for granted suddenly seems unattainable, and their world fragile and uncertain.

Katharina Bruckner, 50, has to deal with many serious cases in the youth welfare office. Even at home she is under stress: Her husband, a surgeon, she sees arm in arm with a younger. And her daughter, who has to go to Marrakech for work, quickly incurs her grandson. In this situation, school psychologist Schubert asks her for help: The city-renowned architect Bremer has appeared with him with her seven-year-old son because of its over-activity in school. The boy looks scared, claims that the Bremer is not his mother, suddenly seems to have disappeared.
