This is a series for German TV that was spread over a period of years and now rolled into 1 season on MHz. It's your average cop duo show. The acting is variable, and the plot lines all over the place. Most are very complicated with numerous characters to the point where the viewer needs a spreadsheet to track who's who! Some of the events just seem to happen in order to get resolution of the case but without any logical explanation. Throughout the years, the actors playing the same supporting roles, seem to change, adding a confusing dimension to the series as well. It's a watchable series but not a stellar one.
