1963: A lawyer is found dead in a hotel room in Granada, in the grey year of the flood, when, for the police, suicides will have the monopoly in death by violence. If the reality were less real than cinematic, one would talk of the case of the bachelor suicides. How does old Commissioner Polo—telecommunications engineer, pioneer in vigilance, prophet of visual and telephonic espionage—see all this from behind his 13 dioptre lenses? Two women. Two close friends who, as the wittiest of the two says, belong to the homosexual circle: the one-sex world, exclusively male and patriarchal. These are the happy years of electronic Anglo-americanization and the Soviet-American conquest of space, of pinball and the jukebox, the origin of the future, and the guardians of the Law don't hesitate to use murder to maintain that order.
