Das fliegende Klassenzimmer

When 13-year-old Martina (Leni Deschner), who lives with her single mother (Jördis Triebel) and her little brother in a Berlin high-rise housing estate, gets the chance to win a scholarship to the coveted Johann-Sigismund-Gymnasium in South Tyrol, she is excited Flame. But as soon as she arrives in the idyllic Alpine town of Kirchberg, the tough Jo (Lovena Börschmann Ziegler), the good-natured Matze (Morten Völlger) and little Uli (Wanja Valentin Kube) make it clear to her that there are rules. The city children in the boarding school and the “externals” from the rural town do not mix with each other; on the contrary, they are enemies, and have been for generations.
Even the adults can't change that: the good-natured boarding school director Justus Bökh (Tom Schilling) tries to be patient, the school director Kreuzkamm (Hannah Herzsprung) tries to be strict, but she doesn't get anywhere, especially since she is also the mother of external leader Ruda ( Franka Roche). And then there is the mysterious dropout, called Non-Smoker (Trystan Pütter), who lives in a train carriage. Martina actually only wants to study for the scholarship. But she immediately finds herself in the middle of the disputes between the rival cliques. She cannot and does not want to abandon her new friends. The plan to settle the eternal dispute with a joint play doesn't work. The gap between internal and external parties is simply too deep. Only one dramatic event changes everything...
