A young criminal investigator named Will Graham, suffering from Asperger's syndrome, is enrolled by the FBI to investigate a strange serial killer who kidnaps his victims - but decided to give back his last victim. Graham's capacity to empathize with everyone else's minds allows him to visualize the crimes how they were committed - but this one eludes his understanding. Another specialist, a psychoanalyst named Hannibal Lecter, is called in to help him. As an estranged team, they investigate the mysterious serial killer - and an even stranger copycat who suddenly appears, giving them new clues as to the true killer's identity and motives: he's a cannibal - but, after discovering his true identity, Lecter warns him the FBI is about to arrest him. The serial killer is killed by Will Graham and his last victim is saved - but has Will Graham gone to deep inside the killer's mind? And who is the strange copycat that appeared right after Lecter was called in to help?
