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.

At the end of winter, there is a game of bowls in the north. The islanders are proud of their bowling ball, which Thies' grandfather found 60 years ago. Only Katharina believes the archaeologist Jens Jeschen, who wants to examine the sphere in a laboratory on the mainland and suspects a Viking grave and treasure on the island, that it is a medieval celestial globe.
