context: Jonathan Harker (Bosco Hogan) is on his way to Transylvania with some documents
  concerning the purchase of a property in England for Count Dracula to
  sign. When his fellow travelers find out where Harker is headed, they beg
  him not to go. Count Dracula (Louis Jourdan) turns out to be handsome and cultured,
  although he sleeps during the day, has hairy palms and sharp fingernails,
  casts no reflection in a mirror, crawls head first down the castle walls,
  does not eat, and his eyes and mouth glow red when he sees blood.Dracula requires that Harker remain at the castle for a month, during
  which time fiancée Mina Westenra (Judi Bowker) worries about Harker and Harker worries
  that he's going mad. Meanwhile, the Westenras -- Mina, sister Lucy (Susan Penhaligon),
  and their Mother (Ann Queensberry) move to their summer home in
  Whitby. Three weeks pass, and Dracula prepares for his trip to England. He
  requests that Harker write a letter saying that he has already left the
  castle and is on his way home. Unable to tolerate being imprisoned any
  longer in the castle, Harker attempts to escape but stumbles into the
  crypt where he finds the three vampiresses and Dracula lying in their
  coffin. His attempt to behead the count fails.Back in London, at Dr John Seward (Mark Burns)'s sanitarium, zoophagist patient
  Renfield (Jack Shepherd) is busy collecting flies and spiders while awaiting "the
  Master's" arrival. In Whitby, a fierce storm is brewing. In the middle of
  the lightning, thunder, torrential rain, and raging seas, a ship is
  beached in Whitby harbor. The next day Skipper Swales is found dead near
  the grave of a suicide. Shortly thereafter, Lucy starts sleepwalking. On
  one of Lucy's sojourns into the cemetery, Mina sees her being embraced by
  a man who promptly disappears when Mina calls out Lucy's name. When Mina
  notices two punctures on Lucy's throat, she blames it on the brooch she
  used to fasten Lucy's shawl the night that Lucy was found sleepwalking.Quincey P. Holmwood (Richard Barnes) comes to Whitby to visit Lucy, his fiancee, who is
  looking pale and growing long canines. Mina learns that Jonathan is in a
  hospital in Budapest and goes to join him. As Lucy is not improving,
  Quincey and the Westenras return to London to consult with Dr Seward,
  whose sanitarium is next to Carfax Abbey, the property purchased by and
  now inhabited by Count Dracula. Unable to make a proper diagnosis, Seward
  sends for Abraham Van Helsing (Frank Finlay) to travel from Amsterdam and have a look at
  Lucy. Van Helsing immediately recognizes Lucy's symptoms as those of a
  vampire in the making. He treats her by making a necklace of garlic and
  sealing the doors and windows of her bedroom with garlic. Unfortunately,
  they don't tell Mrs Westenra what they are doing, and she removes the
  garlic from around Lucy's neck. When a wolf jumps through Lucy's window,
  Mrs Westenra dies of shock, and Dracula enters the room.Lucy is dying. Quincey is called. As he holds her hand, Lucy
  completes her transformation as a vampire and attempts to bite him.
  Moments later, Lucy is dead. Of course, Van Helsing knows that this is
  just the beginning.Meanwhile, Jonathan and Mina, now Mr and Mrs Harker, return to London
  only to find the Westenra house in mourning and Lucy buried in her tomb.
  That night, Van Helsing and Seward visit her tomb but find her coffin
  empty. While walking from the cemetery, they encounter a small child who
  claims to have seen a "bloofer lady" and who has puncture wounds on his
  neck similar to those on Lucy's. Van Helsing and Seward collect Quincey,
  and the three of them return to the cemetery where they find a snarling
  Lucy with blood on her lips. After Lucy returns to her coffin, Quincey
  drives a stake through her heart and Van Helsing fills her mouth with
  garlic and cuts off her head.When Jonathan recognizes the new owner of Carfax Abbey as Count
  Dracula, they send Mina away and make plans to search the Abbey where 50
  boxes of earth were known to be delivered. With a consecrated host, Van
  Helsing sterilizes the boxes, but they find only 29 of them and no Dracula
  (as he is currently paying a visit to Mina's bedroom). The next day Mina comes to see Renfield, who recognizes Mina's
  changed status. Renfield begs to be taken away from the sanitarium, but
  Seward refuses. That night, Dracula comes to Renfield and accuses him of
  thwarting the gift (Mina) that he sent. Dracula kills Renfield and then
  goes to the Harkers' bedroom. While Jonathan lies in a trance, Mina
  accepts Dracula's "kiss." Dracula opens a gash in his chest and makes Mina
  drink. It is at that moment that Van Helsing and Seward enter the bedroom
  and send the Count packing. Mina awakens covered with blood and realizes
  that she is "unclean" when a consecrated host burns her forehead.Van Helsing and Harker track down two deliveries of earthboxes to
  addresses in Purfleet and Mayfair. While they sterilize the boxes, Dracula
  enters. He taunts them, but their crosses and bullets are useless. Dracula
  leaves them speechless when he leaps from a window and escapes. After
  counting the boxes they have sterilized, they realize there is one box
  still missing. Mina tells them that Dracula has taken this box and is
  returning to Transylvania. The fearless vampire hunters follow.Jonathan, Dr Seward, and Quincey follow the river route to the
  castle, while Mina and Van Helsing camp near the castle awaiting their
  arrival. During the night, Mina and Van Helsing are visited by three
  vampiresses. Van Helsing draws a circle around Mina and sprinkles it with
  consecrated hosts to keep the vampiresses out and Mina in. When morning comes, Van
  Helsing goes to the castle and destroys the three vampiresses while Mina
  sleeps in the circle.Along the river, four gypsies load Dracula's last earthbox (with him
  in it) onto a wagon and race toward the castle, Jonathan, Seward, and
  Quincey in hot pursuit. A gunfight breaks out. Quincey is wounded. Three
  of the gypsies are shot, but the fourth manages to drive the wagon the
  rest of the way to the castle, Jonathan, Seward, and Quincey again in
  pursuit. They catch up to the wagon in the castle courtyard and are joined
  by Van Helsing and Mina. As the sun sets, Dracula awakens. But before he
  can rise, Van Helsing stakes him through the heart. A great cloud of dust
  is released, leaving nothing more of Dracula than his clothes. At that
  moment, the burn on Mina's forehead disappears. Dracula is destroyed.
