The main character of the series, psychologist Polina Mikhailova, at first glance seems like an ordinary specialist who can read people and notice details. But Polina has a unique gift: by touching an object or a person, she can see their past. Hiding her abilities from others, Polina gets a job in the police to find her missing sister, and begins working in tandem with Captain Igor Vetrov. Igor is a professional to the core, an analyst and a skeptic who does not believe in any miracles or supernatural phenomena. However, as the investigation progresses, he is forced to admit: he cannot do without Polina's gift, and she herself is not only an unusual person, but also a valuable partner.
