In the late 19th century, amidst the misty backdrop of Eastern Europe, a sinister and suave Count with a haunting allure arrives at a sanitarium overseen by the wise but troubled Dr. Seward. The Count, harboring a nocturnal secret and an insatiable thirst, soon captivates the inhabitants of the sanitarium with his dark charm. Amongst those drawn into his shadowy presence are the beautiful, virginal Mina, her vivacious friend Lucy, and the intrepid Jonathan Harker, who is engaged to Mina. The Count's mystique is undeniable, and as nights grow deeper, the sanitarium becomes the stage for a series of eerie events that suggest a malevolent force at play.

With the patients and residents of the sanitarium under the Count's spell, unsettling occurrences begin to pile up. Lucy's health inexplicably deteriorates, night-time visitations terrorize the sanitarium's occupants, and ancient folklore of the undead starts ringing alarmingly true. Dr. Seward, aided by the famed Professor Van Helsing, delves into a desperate investigation to uncover the true nature of the Count. They discover a connection between the Count's appearance and the terrifying changes overtaking Lucy, and they soon realize they are up against a foe who transcends the bounds of mortal life. As fear grips the sanitarium, the race against time begins to prevent further victims from succumbing to the Count's horrifying desires.
