Karo, Moni and Robert Sonntag – all around 30 – have screwed up their relations and their careers. It's time to take decisions, meaning they all head home to Mom and Dad. However, their parents are not amused. Franz just retired, and Bärbel wants to move to Majorca. The presence of their offspring provokes lies and feints between the siblings and the parents – a dynamic driven by conflict and humor. In time, they all learn that major problems can be a chance to redefine oneself and grow together again.
