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.
