The graduation ceremony of their son Max is no longer a big excitement for Sabine and Bernd Schröder - after all, they have already successfully brought two older sons through high school. Nonetheless, when the youngest offspring moves out, a new chapter in life begins: They finally have plenty of time for each other and common dreams. At least that's the beautiful theory.

And while Bernd continues to bury his head in the sand and hopes for the success of the "sit out" principle, Sabine gets serious. She gives Bernd an ultimatum. Because one thing is clear to them: just continuing like this is out of the question.
