This genre is unfortunately very underrepresented in Germany, so this film by Christian Alvart is a rare pearl. Not to compare with the commercial TV 90-minütern or crime scenes. Satte cinema optics (already in the opening sequence in the factory, I thought, wow, that looks even fat from) very effective soundtrack, very nice detail in love 60s setting, Hamburger local color, a few nice twists, suspense and of course the great actor : the strip should look at. I am angry that I have not seen him in the movies.
