Vladimir Kovalenko is one of those businessmen who "made themselves." He has everything you can only dream of: a well-established business, a beautiful lover, fame. But he does not know his real name and surname: he is a foundling, he received the nickname "Bourgeois" back in the orphanage - for knowing the value of money since childhood.
The elderly criminal authority Semyon Timofeevich Babushkin, about whose thieving talent legends were made up at the time, has not left prison for the last 35 years, preferring it to freedom, where he has no friends or relatives left.
The year is 1967. A series of mysterious murders of women are taking place in Leningrad. An experienced KGB major, Chuzhbin, and a police captain, Fedorov, are assigned to catch a maniac who leaves mysterious signs next to the victims.
Few days before his retirement, an experienced chief investigator gets assigned a new case, where a corpse mysteriously disappears from the morgue. The mortician swears that the man, killed by a train while saving a woman’s life, just got up and left. The woman happens to be a well-connected neuroscientist and she wants to know what happened to her rescuer. The elderly detective and the young doctor make an unlikely duo and their terse relations often get in the way of the investigation. But to get to the truth they have to work together. Intricate plot lines mix three different stories that unravel the mysteries of hundreds of WWII soldiers’ deaths, and even a terrorist plot.
