To uncover a high-profile crime that has put the whole public on its ears, a special group is being created under the Investigative Committee, which is headed by a specific and reasonable investigator Oleg Krylov. To help Krylov, the authorities send psychologist Maria Germanova, a specialist in physiognomy, NLP and the compilation of psychological portraits. Maria has developed her own psychological methodology that allows you to distinguish truth from lies and thereby expose criminals to the open water. The methods of Maria, who had never worked with real crimes before, categorically did not suit Oleg, a seasoned servant of the law. However, it soon becomes obvious that it is thanks to the unusual and "strange", at first glance, psychological techniques that Maria masterfully uses during interrogations, the special department successfully solves a number of complex cases. Krylov is forced to admit the effectiveness of Maria's work in the team and even try to establish a relationship with a strict but sympathetic psychologist.
