In his Baltimore townhouse, the renowned psychiatrist Dr. Hannibal Lecter (Anthony Hopkins) hosts an elegant dinner party that subtly veils a sinister undertone. The conversation flows, centering around the mysterious disappearance of a local musician who, notably, had drawn criticism for hitting several incorrect notes during a concert that Lecter had attended. As the evening progresses, Lecter serves his guests a sumptuous meal and cryptically replies when probed about the meat's origin: > "If I tell you, I'm afraid you won't even try it."
After the dinner, the young and talented FBI agent Will Graham (Edward Norton) pays a visit to Lecter. They are engaged in developing a psychological profile of a dangerous local serial killer. As the investigation unfolds, it surfaces that the madman displays a gruesome pattern—removing edible parts from his victims, such as kidneys and livers—prompting Graham to suspect a more horrific truth: the killer might actually be a cannibal.
In the midst of their consultation, Graham uncovers damning evidence linking Lecter to the heinous murders. Tensions escalate when Lecter, confronting the implications of Graham's discoveries, launches a sudden attack, grievously wounding him before Graham manages to overpower the brilliant but deranged psychiatrist. Following this incident, Lecter is sentenced to life imprisonment within a high-security institution for the criminally insane, while Graham is left to grapple with the profound psychological scars of the encounter, leading him to retire from the FBI.
Years later, the emergence of a new serial killer—dubbed the Tooth Fairy—complicates matters anew. The killer stalks and mercilessly slaughters apparently random families on successive full moons, creating a wave of terror and urgency. In a desperate bid to apprehend the murderer before a potential next victim is claimed, Special Agent Jack Crawford appeals to Graham for assistance. Haunted by guilt over the potential loss of another innocent family, Graham begrudgingly agrees to re-enter the fray.
As he begins to sift through the evidence and crime scenes, Graham recognizes that many of his past successes in catching criminals had been greatly aided by his collaborations with Dr. Lecter, prompting him to seek the psychiatrist's help once more. Meanwhile, the Tooth Fairy is revealed to be a deeply troubled man named Francis Dolarhyde (Ralph Fiennes), whose schizophrenia and twisted admiration for Lecter fuel his horrific actions. Dolarhyde, self-identifying as "The Great Red Dragon" due to an obsession with a painting by William Blake, is unable to rein in his violent and sexual impulses, which spiraled from years of brutal abuse by his grandmother.
Graham's investigation faces further obstacles with the presence of Freddy Lounds, an insatiable reporter from the tabloid Tattler, who relentlessly pursues leads regarding the Tooth Fairy. The tension heightens when a secret correspondence between Lecter and Dolarhyde is unearthed. Lecter coldly reveals Graham's home address, placing the lives of Graham's wife, Molly (Mary-Louise Parker), and son Josh (Tyler Patrick Jones) in peril. To ensure their safety, Molly and Josh are swiftly relocated to a secluded farm belonging to Crawford’s brother.
In a fraught game of psychological chess, Graham strives to intercept the communication between Lecter and Dolarhyde while shielding the vulnerable Graham family. Lecter, however, deftly manipulates the situation, boosting the stakes—his cooperation in capturing the Tooth Fairy hinges on a first-class meal in his cell and the restoration of his reading privileges. In a ploy to provoke Dolarhyde, Graham gives an interview that diminishes the killer in public view, a calculated move designed to bait him further. Yet, the malevolent Dolarhyde retaliates by kidnapping and viciously torturing Lounds to force a public recantation of Graham's allegations, showcasing his reckless brutality when he gruesomely mutilates Lounds before ultimately setting him ablaze.
Amid this chaos, Dolarhyde's burgeoning relationship with a blind co-worker, Reba McClane (Emily Watson), becomes a pivotal layer in the unfolding story. Despite his violent urges, Dolarhyde finds solace in Reba, leading to a tender but conflicted romance that causes him to battle against his darker inclinations and the haunting presence of the Red Dragon. The complexity of their relationship brings forth a chilling tension as Dolarhyde attempts to shield Reba from his monstrous identity.
As the investigation progresses, Graham uncovers the startling realization that the killer's familiarity with the victims' homes stems from his access to the home videos processed by the video editing company where Dolarhyde works. Time runs short as Dolarhyde, sensing he’s narrowing in on him, visits Reba one last time only to discover her companionship with another co-worker, leading to a violent confrontation that spirals into chaos.
The eventual encounter between Graham and Dolarhyde escalates into a heart-pounding climax, culminating in a bitter struggle within Graham's own family home. As the two engage in a deadly dance, Graham’s quick-thinking tactics become the difference between life and death for his son. The tension peaks when chaos breaks out, resulting in both profound loss and the haunting consequences of Dolarhyde's violent quest as Graham must confront his own traumas and the specter of Lecter’s manipulations.
In the aftermath, Graham receives a cryptic letter from Dr. Lecter, reminding him of their intertwined fates, while Lecter yearns for contact with a new agent at the FBI. This chillingly orchestrated web of violence, psychological battles, and deep-seated emotional scars highlights not only the intricate dance between predator and prey but delves into the very fabric of humanity and the darkness that lies within.
