In the five seasons Specht is transferred frequently and experiences the quiet town of Celle, a boarding school on an island (Krähenwerder), the political situation shortly after the Wende in Potsdam and Berlin, and at the end of the series, the Bavarian countryside, again in a boarding school. The exteriors were mostly shot on the island of Scharfenberg in Berlin-Tegel, which also houses a Gymnasium (school type) with adjacent school farm.
