context: In Whitby, England in 1913, Count Dracula (Frank Langella) arrives from Transylvania via the ship Demeter one stormy night. A sickly Mina Van Helsing (Jan Francis), who is visiting her friend Lucy Seward (Kate Nelligan), discovers Dracula's body after his ship has run aground. The Count visits Mina and her friends at the household of Lucy's father, Dr. Jack Seward (Donald Pleasence), whose clifftop mansion also serves as the local asylum. At dinner, he proves to be a charming guest and leaves a strong impression on the hosts, Lucy especially. Less charmed by this handsome Romanian count is Jonathan Harker (Trevor Eve), Lucy's fiancÃ©.
  Later that night, while Lucy and Jonathan are having a secret rendezvous, Dracula reveals his true nature as he descends upon Mina to drink her blood. The following morning, Lucy finds Mina awake in bed, struggling for breath. Powerless, she watches her friend die, only to find wounds on her throat. Lucy blames herself for Mina's death, as she had left her alone.
  At a loss for the cause of death, Dr. Seward calls for Mina's father, Professor Abraham van Helsing (Laurence Olivier). Van Helsing suspects what might have killed his daughter: a vampire. Moreover, he begins to worry about what fate his seemingly dead daughter may now have. Seward and van Helsing investigate their suspicions and discover a roughly clawed opening within Mina's coffin which leads to the local mines. It is there that they encounter the ghastly form of an undead Mina, and it is up to a distraught van Helsing to destroy what remains of his own daughter.
  Lucy meanwhile has been summoned to Carfax Abbey, Dracula's new home, and soon she reveals herself to be in love with this foreign prince and openly offers herself to him as his bride. After a surreal "Wedding Night" sequence (employing lasers and shot by famed James Bond title sequence designer, Maurice Binder), Lucy, like Mina before her, is now infected by Dracula's blood. However, the two doctors manage to give Lucy a blood transfusion to slow her descent into vampirism, but she remains under Dracula's spell.
  Now aided by Jonathan, the elderly doctors realise that the only way to defeat Dracula (and save Lucy) is by destroying him. They manage to locate his coffin within the grounds of Carfax Abbey, but the vampire is waiting for them. Despite it being daylight, Dracula is still a very powerful adversary. Dracula escapes their attempts to kill him and bursts into the asylum to free the captive Lucy. While there he murders his one-time slave, Milo Renfield (Tony Haygarth), for warning the others about him. Dracula now intends for him and Lucy to return to Transylvania together.
  In a race against time, Harker and van Helsing just manage to get on board a ship carrying the vampire cargo bound for Romania. Below decks, Harker and van Helsing find the Count's coffin; upon opening it they see Lucy sleeping beside Dracula. Again they try to destroy him, but the Count awakens and once more fights with them. In the struggle, van Helsing is wounded by Dracula as he is impaled by the stake intended for the vampire. As the enraged Count now turns his attention to Harker, van Helsing throws a hook (attached to a rope, from the ship's rigging), into Dracula's back. Harker seizes his only chance and hoists the Count's body up through the cargo hold and into the sunlight above. Dracula then suffers a slow and painful death as the solar rays burn his body.
  Lucy, now apparently herself once more, reaches out to Harker, who stares at the mortally wounded van Helsing. At this moment, she looks up to see Dracula's cape flying away in the wind, and smiles enigmatically.
