A new case from the profiling department is the capture of a serial killer who is “recreating” the masterpieces of the famous Renaissance artist Caravaggio. “Medusa”, “Narcissus”, “Bacchus”, “Fortune Teller” - this is an incomplete list of “paintings” that law enforcement officers will find in art museums near Moscow. After the third murder, international expert Rasmus Birk is brought in to investigate, and just by looking at the crime scene, he realizes that his former patient is leaving messages in the museums. Once he considered him not dangerous to society, but now his professional mistake haunts him. Birk considers it a matter of honor to catch the killer.
