The film opens on a desolate gas station at night, where a woman is suddenly ambushed by a supernatural figure. She manages a desperate, fiery defiance, lighting the attacker on fire, only to watch the flames fail to stop it as the creature drinks her blood in a brutal, silent moment of predation.
A trio of college freshmen — Charley Brewster, Amy Peterson, and Evil Ed Bates — travel to Romania for a semester abroad, chasing new experiences and the thrill of distant cultures. Charley carries the sting of recent infidelity, a rift with Amy that lingers as they navigate a land steeped in old legends. The mood shifts when Charley spots their enigmatic Romanian art teacher, Gerri Dandridge, in compromising, intimate situations, first with a woman and then with a man, both times captured in his wary gaze. Gerri’s beauty proves to be more than skin-deep; Charley begins to sense something chillingly inhuman behind her veneer.
As nights deepen, Charley’s suspicions crystallize into a chilling revelation: Gerri moves with supernatural speed, strength, and a predatory intent. He witnesses a blood-soaked ritual as Gerri returns home with a woman and feeds on her, draining her into a tub and bathing in the crimson waters. The sight confirms Charley’s worst nightmare: Gerri is a vampire. His fear intensifies when Gerri catches him observing from the shadows, and she begins to manipulate him with a subtle, dangerous psychic power that unsettles both Charley and Amy.
Charley, desperation sharpening his sense of danger, infiltrates Gerri’s house with a plan to confront her. He discovers a coffin and a bathtub filled with blood, a tableau that seems to restore Gerri’s youth and vitality each time she bathes in it. When Gerri returns home with a hypnotized companion, she seduces and drains the woman before sliding into the blood-filled tub herself. Charley escapes, only to find Gerri waiting again at Amy’s apartment, where Amy remains skeptical of Charley’s increasingly urgent warnings. The pair depart in fear, while Gerri’s unsettling charm and powers linger like a shadow over their fledgling relationship.
Determined to prove his theory, Charley enlists [Evil Ed Bates] and Amy to investigate ancient lore that could explain Gerri’s uncanny nature. Their online search leads them to a notorious figure of vampire myth, Elizabeth Bathroy, and a parallel legend that suggests a vampire of centuries could only be freed from a curse by a ritual bathed in blood. The trio learns that Bathroy’s bodyguards died in a brutal-once, and Bathroy herself survived by becoming one of the undead. The key detail emerges: Bathroy seeks to bathe in the blood of a virgin born at midnight under a blood moon, a ritual that would extinguish her curse and restore daylight for her to walk freely again.
Eager for a glimmer of legitimacy, the group tracks down Peter Vincent, a host of a popular horror/ghost-hunting show who’s currently filming in Romania. Peter is dismissive of their claims when they burst into a strip club, but the trio persuades him for a fee — $3,000 — to join them in their stalker-like pursuit of Gerri. A reluctant alliance forms, and Amy’s unexpected decision to tag along strengthens the unlikely party as they descend into the labyrinthine subway tunnels.
In the subway, Gerri awaits, her eyes shifting to a blood-red hue. Peter senses the danger first, and he escapes the car, leaving the other three behind. Evil Ed makes a sacrificial move to shield them, buying time as Gerri feeds, transforming him into her latest minion. She uses her uncanny radar-like powers to locate Amy and Charley, ripping through walls and windows with a sonic scream as the pair scramble toward a church beneath the city.
The church becomes a fragile sanctuary, a place where Gerri cannot pursue. A brutal moment follows as Gerri slashes Amy’s leg, testing the resilience and the will of her would-be savior. Yet in the sanctity of the church, Amy’s blood proves to be a critical ingredient; the vampire’s curse hinges on that very blood, and Gerri recognizes the significance of Amy’s lineage and its potential to break the spell.
A taxi ride to the airport marks a tense turning point. Gerri reappears with terrifying speed, abducting Amy and revealing that she intends to bring Amy to Bathroy’s castle. Charley seeks out [Peter Vincent], who at first refuses to help but is swayed by the practicalities of vampire lore. Peter equips them with wooden stakes, garlic powder, and holy water, and hints at a crucial, dawn-bound principle: a vampire killed at dawn could restore humanity to others turned by that vampire the previous night.
In a cruel twist, Gerri bites Amy, turning her into a vampire and revealing the ritual’s true price: Amy must kill Charley, the one she loves, to break Gerri’s curse. Gerri promises continued immortality, shielded from sunlight, if the ritual succeeds. Charley, armed with tools and a stubborn resolve, races to confront the threat as the countdown to sunrise tightens.
The final confrontation erupts in a brutal, chaotic scuffle. Evil Ed returns to menace Charley, only to be defeated by a fatal blast of holy water that annihilates his insides. Charley locates Amy, but love overpowers suspicion; Amy’s new vampiric bloodlust turns Charley, though his transformation is tempered by the fact that he was bitten by Amy rather than by Gerri’s own hand. Gerri escalates, attacking with all her supernatural prowess, and Peter arrives to turn the tide, his aim imperfect as he stabs but fails to pierce Gerri’s heart.
Dawn draws near, and the sun’s bright, unforgiving glow presses in. Desperation fuels Charley’s last-ditch move: a sonic-scream that shatters the room’s windows and unleashes a flood of daylight into the chamber. The church’s blood vault becomes a temporary shield as Charley and Amy scramble to safety, ducking under the thick, lifeblood-filled bath to escape the sun’s deadly kiss. Gerri’s curse shatters in the light, and the two lovers—now free from the curse and returned to humanity—mourn the loss of Evil Ed, their steadfast ally.
In a final, triumphant breath, Charley and Amy step into the dawn together, their bond proven stronger than the night’s horrors. Their kiss closes the credits, a quiet vow that love can endure even when alight with legends and the shadows of Romania.
