This TV series, transmitted between 5 and 7 in the early evening slot on the ARD, was a fairly accurate reflection of actual police work at the time. The action content was ever so slightly revved up for entertainment purposes, and each episode had a self-contained story, but other than that it does not feel too far removed from reality TV. Apparently there was indeed some collaboration with Hamburg's police, and - probably not entirely unconnected to that - the odd episode here and there feels like a police education video.
Several episodes were filmed outside Germany, in France and Japan, on the pretext of a police exchange programme (we always keep our leading man), and these episodes have aged much more badly than the rest of the series.
