Boris Krylov is a top-class criminologist. In his work, he uses paradoxical and non-obvious methods that help him unravel even the most complex crimes, for which his colleagues call him a modern Sherlock Holmes. Due to a divorce from his wife, a brilliant detective leaves the police and makes a living as a consultant on the set of detective series. But when his father, a famous surgeon, dies in a car accident, and he himself is seriously injured, Krylov begins his own investigation. My instinct tells me that the accident was planned: before his death, his father tried to tell him something. So Boris returns to his profession and gets a job as an expert in the investigative department, which is headed by Major Anna Voskresenskaya. Anna was once a student of Krylov. Now Krylov and Voskresenskaya will have to work together. While solving crimes, the heroes deal with their past and feelings for each other.
