Katharina Hendriks loves her job as headmistress of a vocational school. However, cutbacks threaten to spoil her job, as does the arrival of her brother Erik as a guest teacher. Their visions clash and this has consequences not only for the atmosphere, but also for the pupils.

The Flensburg vocational school is in a crisis mood: unless a miracle happens at the open day, the gastronomy class is threatened with extinction! Principal Katharina and her teaching staff have to come up with an idea to get the necessary registrations. What could be more obvious than relying on the show talent of guest lecturer Erik? The food blogger's idea of processing a beef from head to tail promises to be a live spectacle. However, the free spirit goes it alone. Without consulting the structured director, he invites her sister, celebrity chef Antje Beringer, to be his star guest! Now Katharina, who has broken up with her, has to face an involuntary reunion.
