Tanja Sorg owns an Opel Nakkita GTC a chic girls' coupe tuned at the factory and with its
paint job an absolute one-off.Hans Burgmeister a moderately successful traveling salesman
drives too fast into a densely populated residential area in Porta Westfalica loses control of
his SUV and rams Tanja's beloved Nakky.Two days later he is dead run over in a field and all
the evidence points to Nakky as the murder weapon.This is the beginning of an absurd series of
murders in which detective inspector Charlotte Bauer has a lot to gnaw on. Absurd because you
can kill someone with a Nakkita but you certainly can't run them over because the coupes of
the GTC series with their sports chassis are much too low over the road for that. The victims
of the murders however have tire marks on their faces and in the courtyard of Nadja
Pfeifer's workshop there are literally piles of damaged cars and wrecks of this type which
after the respective accidents are observed undamaged by witnesses during the murders.
