In the luxurious mansion of the scandalously notorious restaurateur Lebedev, famed for his insatiable appetite for women’s hearts, the body of a young woman is discovered. The investigation is assigned to Detective Kira Avdeeva—a woman with a sharp mind and a difficult temperament. At that moment, her own life is undergoing a painful turning point: a recent breakup with her beloved has left a bitter wound in her heart—the man not only left her, but also did not hesitate to publicly humiliate her as a final farewell. At first glance, Lebedev’s guilt seems beyond doubt. However, the investigation soon takes an unexpected turn: it emerges that on that same ill-fated evening, his son vanished without a trace. Plunging into an abyss of secrets and contradictions, Kira gradually realizes that this case is inextricably linked to her personal tragedy, as though an invisible thread binds another person’s misfortune to her own emotional pain.
