When Peter Faber joins Jan Pawlak and Rosa Herzog in the early morning, the forensics team is almost done with their work. Tram driver Hamza Arkadas was stabbed while working the night shift. There are no witnesses, but the images from the surveillance camera show how Arkadas was first provoked and then attacked by a young passenger. The perpetrator pointed his face aggressively at the camera before fleeing, but the recordings are of little help at first. He does not seem to be known to the police, and prosecutor Matuschek does not want to go public with the pictures yet. Rosa Herzog, who took over the acting management of the homicide squad in Faber's absence, gets support from police officer Beate Gräske. She is a "super-recognizer" with the special ability to recognize faces - much better than her colleagues and the technology can do. With the help of surveillance cameras, she sets out to track down the perpetrator.
