This is Butsch Schulz and Viola Delbrück's first case together. The unlikely duo are based in Görlitz, Germany's easternmost town. As they hunt for a young German-Polish couple, they have to put differences aside and work together.
Despite the success of their first case together, Butsch and Viola are barely speaking. Not good, as right now they are needed as a team. There's not only a serial killer at large in Görlitz, but also Viola's soon-to-be-ex husband.
