Created by Sven S. Poser and Martin Eigler, this popular crime series has been on the air since 2009. Nina Petersen is an energetic police inspector and very pragmatically. In the latest case, Nina investigates a crime before it is committed. A co-worker confides that she and a friend feel they are being watched. When a murder takes place, and it turns out that the victim had the same suspicion, Nina and her team search for a connection to the phantom.
