With his vision of showing police work in a way that is realistic, exciting, and human, crime expert Jürgen Roland created Großstadtrevier, one of the most beloved police series on German television. In the early seasons Arthur Brauss leads the investigations, and from season six onward Jan Fedder takes over at Hamburg’s 14th precinct. Now change is coming again. Paul Dänning has left the team, and Police Chief Inspector Lukas Petersen joins, but his start is far from easy. Hannes Krabbe digs up an old story that haunts him, as the newcomer is remembered as the so-called Dike Sheep Killer of Hohenhorst.
