Carla Nowak (Leonie Benesch) is a dedicated, idealistic young teacher in her first job at a middle school. Her relaxed rapport with her seventh-grade students is put under stress when a series of thefts occur at the school, and a staff investigation leads to accusations and mistrust among outraged parents, opinionated colleagues, and an enigmatic student. Caught in the middle of these complex dynamics, the more Carla tries to do everything right, the more desperate her position becomes.
