Gerri Dandridge, a charismatic and seductive college professor in Romania, is secretly a centuries-old vampire yearning for fresh blood to sustain her eternal existence. Meanwhile, teenager Charley Brewster travels abroad on a study-abroad trip with his skeptical best friend Ed Bates and his heartbroken ex-girlfriend Amy Peterson, still reeling from their recent painful breakup. While touring the ancient gothic city, Charley witnesses Gerri luring a helpless student into the shadows and feeding on her. Convinced of the professor’s true nature, Charley desperately tries to warn his friends, but Ed dismisses his claims as post-breakup paranoia, and Amy believes he is simply hallucinating due to stress. Undeterred, Charley researches local folklore and discovers that Gerri is the legendary descendant of Elisabeth Bathory. He seeks help from Peter Vincent, a washed-up, cynical host of a cheesy late-night reality horror show who is filming in the city. Peter initially scoffs at Charley’s wild tales, viewing the boy as an annoying fanboy, but he eventually agrees to investigate when a series of unexplained disappearances plague the university campus. Tension escalates when Gerri sets her sights on Charley, using her hypnotic allure and terrifying supernatural abilities to isolate him from his peers. She targets Amy, kidnapping her to use as bait in a twisted ritual designed to break Charley’s spirit and complete Gerri’s ultimate
transformation into a day-walking immortal. Driven by guilt and a desperate need to protect Amy, Charley and Peter break into Gerri’s heavily fortified, subterranean lair, which is guarded by her fiercely loyal, bloodthirsty thralls. Inside the labyrinthine catacombs, Ed is captured and turned into a vampire, forcing Charley into the heartbreaking dilemma of having to fight his
former best friend. Ed attacks Charley with brutal ferocity, but Charley manages to temporarily incapacitate him using UV light. As the ritual reaches its climax, Gerri prepares to drain Amy completely. Peter confronts Gerri directly, using his theatrical props—which unexpectedly turn out to have real mystical properties—to stall the ancient beast. In a chaotic final showdown, Charley uses a stake blessed with ancient artifacts to pierce Gerri’s heart just as the first rays of dawn pierce the damp cavern ceiling. Gerri disintegrates into ash, freeing her thralls and breaking the supernatural curse. As the dust settles, Charley, Amy, and a deeply shaken Peter escape the ruins, their bonds forever forged in terror.
