The film, like Diva, deals with the hunt for evidence (video here, audio in Diva) of a corrupt policeman. Both films have a leads female named Nadia, and in the scene with Marconi in bed, he is watching a performance of the aria featured repetedly in Diva "La Wally". There is also a corrupt duo of cops, one bald, and a scene with an old roulette - just like Diva.
