Found in the German Camera Obscura DVD collection. Eriprando Visconti, nephew of Luchino, made 9 movies between 1962 and 1982. Here we have a poliziottescho which is not quite a poliziottescho. There isn't a single car chase in it, a masterstroke in 1976! There's also Michele Placido's strange dream, one of the best dream sequences I ever saw at the movies, that is not so politically correct here. Recommended.
