A confused girl with amnesia, a knife and a jacket covered in blood, arrives at Angelika and Franitschek's office for help. She might be involved in a stabbing at Nordbahnhof that Maja and Zlatk are investigating, as she can be seen in the surveillance videos. Angelika is convinced of the girl's innocence, but lies to the police about the bag full of money she was carrying when they first met. The investigations lead them to the train station where stray kids live under a social worker's rules.
