A substitute teacher catches a thief in her school and decides to handle it herself. Her tidy sense of justice detonates across the faculty, the students, and one boy in particular. Doing the right thing has never looked more like a slow-motion catastrophe.

Carla Nowak teaches math and gym at a German middle school where a string of petty thefts has the staff on edge. The administration questions students. Carla finds that approach ugly and decides to run her own quiet investigation. She leaves a jacket with cash in the teachers’ lounge and records the room with her laptop camera. The footage implicates a colleague, and from that single act of certainty the film builds a chamber drama about how institutions protect themselves and how good intentions metastasize into ruin.

Leonie Benesch plays Carla as a woman who believes in fairness and cannot stop pulling threads. She holds her body rigid through every confrontation, smiling when she should retreat, escalating when she should let go. Eva Löbau plays Friederike Kuhn, the accused administrator, with a wounded poise that never resolves into guilt or innocence. Leonard Stettnisch plays Oskar, Kuhn’s son and Carla’s brightest student, and he turns a wronged child into the film’s most dangerous force. The relationship between Carla and Oskar curdles from mentorship into siege.

İlker Çatak directs from a script he wrote with Johannes Duncker, and he shoots the entire film in the boxy Academy ratio. The narrow frame traps Carla in hallways and classrooms and makes every doorway feel like a checkpoint. Marvin Miller’s score saws and pulses like a thriller, scoring faculty meetings as if they were heists. Çatak cuts conversations on the beat of a flinch, so each scene tightens before it releases. The production design keeps the school clean and bright, which makes the paranoia underneath read as institutional rot rather than melodrama.

This is a film about the impossibility of clean justice inside a system designed to manage appearances. Carla wants the truth and a fair process, and the school wants neither. Çatak refuses to grant her the vindication she keeps reaching for, and he refuses to let the audience off with a villain. The movie ends on an image of authority that solves nothing and explains everything.
