The Wolfman

In 1891, Ben Talbot is killed by a fierce creature in the Blackmoor woods. Gwen Conliffe, Ben's fiancÃ©e, has contacted his brother Lawrence, a Shakespearean actor, saying that Ben disappeared. Lawrence returns to his family's estate in Blackmoor where he has an uneasy reunion with his estranged father, Sir John. Lawrence discovers Ben's mutilated body kept in a slaughterhouse. At the local pub, Lawrence overhears the locals discussing the killing. Many blame Gypsies who are camped outside the town, while another patron claims there was a similar murder several decades earlier and a werewolf was the suspected killer. He has flashbacks as he tours his family's home that his mother, Solana, committed suicide when he was a boy. Lawrence saw his father standing over her dead body; afterwards he was sent to an insane asylum in London for having to suffer from delusions.
Lawrence visits the Gypsies during a full moon. The local townspeople raid the camp to confiscate a dancing bear they believe is the killer, but a werewolf attacks the camp and bites Lawrence before being chased away by local hunters. A Gypsy woman named Maleva sutures his neck wounds, but her daughter insists the now cursed Lawrence should be killed before he destroys other lives. Maleva refuses, saying he is still a man and that only a loved one can release him.
Lawrence recovers unnaturally quickly, and develops heightened vitality and senses. His father's servant, Singh shows Lawrence a set of silver bullets and implies that something monstrous is loose in Blackmoor. Inspector Aberline arrives to investigate the recent killings, and suspects Lawrence is responsible based on his mental history and portrayals of mentally-ill characters. Lawrence sends Gwen away to London for her own safety. He follows his father to his mother's crypt, where Sir John locks himself in a room alone as he gives a cryptic warning to Lawrence. Lawrence then undergoes a painful transformation into the Wolfman before running off into the woods and killing the hunters stationed there.
Aberline and the police arrest the now human Lawrence. Taken to the same asylum he was committed to as a child, Lawrence is subjected to torturous treatments by Dr. Hoenneger. Sir John visits Lawrence and explains that many years before while hunting in India, he was bitten by a feral boy infected with lycanthropy. Lawrence realizes his father, as a werewolf, killed his mother and his brother. Knowing that Lawrence would never be believed, he confesses before leaving his son at the asylum permanently.
Dr. Hoenneger conducts an evening lecture with Lawrence as a case study and assures Lawrence that he is only a werewolf in his imagination, seeking to prove it by putting him on display during the full moon. As the full moon streams through the window, Lawrence transforms into the Wolfman and goes on a rampage throughout the lecture hall and London, with Aberline in pursuit. The next day, the now-human Lawrence goes to Gwen's antique shop for help. They realize they are falling in love and share a passionate kiss. Aberline arrives and searches the shop, but Lawrence has already escaped to Blackmoor.
Lawrence arrives at Talbot Hall and finds Singh's mutilated body. He loads a gun with Singh's silver bullets, but when he attempts to shoot his father, he learns that Sir John had removed the powder from the cartridges years ago. The Talbots fight, transforming into werewolves when the full moon rises and setting Talbot Hall on fire. Lawrence kills his father as Gwen and Aberline arrive. Aberline attempts to shoot the Wolfman, but is bitten instead. Gwen disrupts the shot and flees with Aberline's revolver.
The Wolfman pursues Gwen and traps her above a gorge. She pleads with Lawrence, whose consciousness recognizes her. As he hesitates, the hunters approach, distracting the Wolfman long enough for Gwen to shoot him. Lawrence reverts to human form, thanks Gwen for setting him free and dies in her arms. Aberline arrives with the hunters, but as he looks at the moon, he realizes his inevitable fate. As Talbot Hall burns in the distance, a howl is heard in the distance.
