On the rain-slicked streets of New York, a string of nocturnal killings unsettles the city. Each murder unfolds under the glow of a full moon, leaving behind disfigured, cannibalized remains and witnesses who describe a nightmarish, monstrous figure moving through the shadows. Daily World reporter Lee Taylor becomes obsessed with cracking the case, chasing rumors and timelines through a city that seems to slide from ordinary crime into something far more unsettling. Taylor’s instincts push him toward the medical community, where the case appears to connect to the enigmatic Dr. Jerry Xavier and his prestigious medical academy. The police, meanwhile, are not just pursuing a killer; they want to pry loose the secrets hidden within Xavier’s institution, secrets tied to a blood-chilling brain scalpel that appears to be a signature of the murders.
As the investigation widens, the field of suspects narrows to a cluster of doctors whose peculiarities and obsessions align with the crimes. There is Dr. Wells, an amputee who has studied cannibalism from a scholarly distance and could be seen as a man driven by a chilling curiosity. Then there is Dr. Haines, whose sexual perversion and voyeuristic tendencies add a disturbing layer to the case. Dr. Duke is a grumpy paralytic, while Dr. Rowitz has been conducting unsettling studies into the psychological effects of the moon. With each new detail, the case grows more tangled, and the tension between justice and science becomes almost unbearable.
The police board immobilizes Xavier with a grim ultimatum: 48 hours to unmask the killer by Xavier’s own methods. Taylor’s investigation intersects with Xavier’s family life, and he encounters Joanne Xavier, the doctor’s emotionally guarded daughter. Joanne’s hostility toward him grows when she learns that Taylor’s initial reporting helped derail Xavier’s first attempt to locate the killer. Despite the friction, Taylor finds himself drawn to Joanne, surprised by how their wary glances and guarded conversations start to reveal a shared obsession with uncovering the truth behind the gruesome acts.
The dramatic confrontation comes to a head at Xavier’s secluded beachside estate, where a chilling, unorthodox experiment is staged. Five men—every physician suspect except Dr. Wells—are wired into an elaborate system that monitors their heart rates as they witness a reenactment of a murder carried out by Xavier’s loyal staff, Otto and Mamie. The motive behind this grim performance is to coax the guilty party into a reaction that will reveal itself under the recording apparatus. The sudden blackout that follows razes the room’s certainty and shatters the planned transparency of the exercise. When power returns, the room discovers that Dr. Rowitz has been killed by a brain scalpel—precisely the method seen in the earlier murders—and his body is revealed as cannibalized, confirming the killer’s proximity and cunning.
The following night, the experiment resumes with Joanne stepping into Mamie’s part when fear makes the maid retreat. The others remain handcuffed to their seats, the doors locked, and the ominous sense of surveillance thick in the air. In a daring, sly twist, Dr. Wells slips away from the recording cabinet and slips into a hidden laboratory where he can transform himself using “synthetic flesh” to become the Moon Killer. He then brutally dispatches Otto and announces his long-planned plan to harvest living human flesh, with Joanne as his next intended victim. The air becomes electric with danger as Wells reveals his true identity and his chilling intent, and the room tightens with fear and disbelief.
Amid the growing dread, the everyday courage of reporter Taylor surfaces. He hides among a display of wax figures, watching Wells’ every move as the killer advances toward Joanne. The moment of truth arrives in a tense, physical struggle: Taylor erupts from his concealed position and pummels Wells in a brutal fight. As the struggle spills toward the edge of the scene, Taylor grabs a kerosene lamp and hurls it toward Wells, igniting a blaze that drives the killer toward a window and out into the night. Wells crashes through the glass and tumbles from the cliff to the ocean below, consumed by flames as the waves churn in the darkness.
With the danger finally contained, Taylor returns to his newsroom, where the day’s events crystallize into a story that could change many lives. He files the report with a relentless sense of duty, and in his closing line he suggests that the newspaper open space in the marriage section—not for a typical union, but for a future that could be forged between Joanne and Taylor themselves. The city breathes again, the moon wanes, and the mystery that began with a surge of fear ends in a hard-won, morally complex victory that tests the limits of science, journalism, and the human heart.
