Will Graham is a former FBI agent who captured the infamous Dr. Hannibal Lecter and was almost killed in the process; he is so traumatized by the event that he retires from the FBI. His former boss, Jack Crawford, calls him out of retirement to help find a killer called "The Tooth Fairy" who is murdering entire families. Graham is a profiler who has an uncanny ability to enter the mind of a killer and think and feel as he does. Some would say that what Graham really does is to insert the serial killer into his own mind at a much greater risk to his own mental health. Doctor Lecter confronts him about this knack during a trolling visit from Graham and points out something that Will already knows but doesn't like to admit: The reason Graham caught Lecter is that they are just alike.
