The brilliant career of Marina Kolyvanova, a successful headhunter, or, to put it simply, a specialist in luring top managers from one company to another, is about to collapse. After a stressful interview she conducts, a candidate for a leadership position dies suddenly and strangely. The investigator is sure that Marina exceeded her authority and drove the man to suicide. Savely Vasin, a young energetic employee of the prosecutor's office, who is in love with Marina and is ready to do anything for her safety, comes to the girl's aid. However, his steel muscles and a pistol are clearly not enough here - to unravel the tangle of mysterious events, find out the cause of several strange deaths and find a sophisticated criminal, a powerful intellect is required. Then, after persistent persuasion from Vasin, his mentor, the uncrowned king of detectives, an honorary retired employee of the prosecutor's office and an avid chess player, Yuri Ivanovich Boyko, gets down to business.
