What use is a good Abitur if the climate is changing? For 17-year-old high school student Lilly, there are more important things than school. It looks correspondingly bleak with their admission to the Abitur. While father Martin fails with a bang to lure her with a dream trip, mother Nina makes an unusual deal: if Lilly really crams from now on, her parents will in return help protect the climate. From now on, only fresh food will be cooked at home, lavender will replace industrial washing powder and you can go to work by bike. There are only exceptions for little brother Tom. But the road to an emission-free life is not a sure-fire success. After weeks, agency owner Nina and chief physician Martin are not only looking for secret exceptions to the rules, but also get into discussions about their lives up to now. And since Lilly doesn't quite stick to the deal with her parents either, the initially abstract discussion about climate-friendly living escalates into a true family crisis.

Hospital doctor Martin Wilmers and founding publicity agency manager Nina worry their daughter Lili (17) will fail her final gymnasium exams, obsessed with climate actions like Thunberg. They generously offer to live perfectly durably to her absurd standards if she concentrates full-time on hers studies. Finding she cheats massively, Martin does so a bit too but Nina turns eco-extremist herself, demanding to change their whole lifestyle 'to enjoy life' instead of the rat race. Good son Tom desperately asks dad to fix things, including their marriage, so they get their lives back, to little avail, Nina even asks her senior executive Antonio Behrmann to become full partner so she can work part-time.—KGF Vissers
