Watch FilmoFlix. On February 27, 2009, pupil Benjamin Feller commits a crime which he has meticulously described beforehand in a diary entry. He goes to the post office to send the diary entry to his teacher before he shoots his parents and turns himself in to the police. His teacher Esther Fontanel tries to understand the events in retrospect. But as the journal’s addressee, she is increasingly targeted by the police herself.
