Psychiatrist Badr Nour El Din never expected that his work as a police psychological consultant would open all these doors for him that he never thought existed, and that a single session would force him to embark on an arduous journey in the world of psychological crime: from the mountains of Tibet, to the morgue of a government hospital, to the attempts of a paralyzed man to free himself from the shackles of his helpless body, to the story of Jack the Ripper, whose identity has not been revealed until this moment, to a girl seeking to reach her kidnapped twin sister through feelings alone, to a theater actor's adventure with the devil, to a thief who takes nothing but corpses, to a meeting that brings together the most famous criminals of all time. And finally, with a real threat to blow up five of Cairo's most important tourist attractions; a threat from a professional criminal who wants to get rid of Badr, about whom he knows no evidence or information other than his nickname: "The Maestro."
