SAT.1 shows school with all its problems, quarrels and hopes: The focus of the German fiction series are the four teachers Franka, Paula, Yasin and Robin. You work at a comprehensive school in Frankfurt and your students keep you on your toes. And not only that: In addition to the problems of their protégés, there are also the teachers' own challenges. In a world full of helicopter parents, social networks and teenage pregnancies, it's not that easy to find the balance.
