After graduation from the law faculty Yesenia is dreaming to work with Rodion Meglin. He is a mysterious man, lonely investigator with an incredible ability to solve maniac cases. His method is a mystery for everyone. When Yesenia starts being his trainee she begins to realize that the basis of the method is that Meglin himself is a maniac. He feels other maniacs instinctively. He is allowed to eliminate some of them, and look after the others, saving their lives.The love that never meant to happen will go along with the most horrible crimes of the last decade.
