The moral is simple: keep your mouth shut, especially when you're working during the wartime in a factory, which produces racing cars only, or someone can (or even must) get murdered. Not a good movie, not a bad either. The ending is abrupt and artificial, which seems to be a common plague of Third Reich's crime movies. Gustav Fröhlich could never get rid of his silent era mannerisms and overacting. But on the other side, this film is not boring and has to offer some decent plot turns and acting.
