Businessman Sergey Monakhov is very unhappy with how the investigation into the murder of his younger brother, Aleksey, is going. The case has been returned, but the new investigator turned out to be a bore and a cowardly overcautious person. Sergey is absolutely sure that his brother—the Russian patriot—was killed by an “outsider” among the security guards of the dacha settlement where Aleksey lived. Not trusting the official investigation, Monakhov Sr. turns to the famous crime expert, Drongo. The private investigator begins a parallel investigation, not realizing that the final “point” in this tangled matter will be made by… a gynecologist.
