Gigi Marinescu is a police inspector working in the Homicide Department. He is married to Violeta, has a daughter in the third grade at the Music High School and, for over a year now, he has lived with Lulia, a divorced nurse ten years younger than himself, with a child. Eventually, marital, professional and extra-conjugal duties overwhelm him. He is in the position of making a major decision, and the opportunity arises when Horia Zancu, head of the University Hospital's Dialysis Department is murdered. Investigating the case, Marinescu unravels the story behind the murder, a mysterious and sordid series of events over the past thirty years, in which friendship, compromise, betrayal and adultery crisscross. The case does not seem very easy to solve, but the thing that draws Marinescu's attention the most is the adultery, the extra-conjugal relationship, - the thirty-year-old love story between Mrs. Amalia Zancu and a certain Zaharia Aloman – in which the police officer finds similarities with his own romantic extra-conjugal relationship. Thus, the evidence that he gathers during the inquiry, rather than clearing up his speculations and helping the investigation of the case and the murderer's capture, turn out instead to be no more than signs of his own immorality.
