Behind the scenes
Frankenstein's Monster was a creature created from different kinds of body parts belonging to dead people. He (or It) was created by Doctor (later Baron) Henry Frankenstein.

History Edit

Frankenstein Edit

In a European village, a young scientist, named Henry Frankenstein, and his assistant Fritz, a hunchback, piece together a human body, the parts of which have been collected from various sources, including stealing freshly buried bodies in a cemetery, and recently hanged criminals. Frankenstein desires to create human life through electrical devices which he has perfected. He sends Fritz to a school where Dr. Waldman, Henry's old medical professor, teaches, to steal a brain; Fritz drops the normal brain and has to take the brain of a criminal.

Elizabeth, his fiancée, is worried over his peculiar actions. She cannot understand why he secludes himself in an abandoned watch tower, which he has equipped as a laboratory, refusing to see anyone. She and a friend, Victor Moritz, go to Dr. Waldman, and ask Waldman's help in reclaiming the young scientist from his experiments. Waldman tells them that Frankenstein has been working on creating life. Elizabeth, intent on rescuing Frankenstein, arrives just as Henry is making his final tests. He tells them to watch, claiming to have discovered the ray that brought life into the world. They watch Frankenstein and the hunchback as they raise the dead creature on an operating table, high into the room, toward an opening at the top of the laboratory. Then a terrific crash of thunder, the crackling of Frankenstein's electric machines, and the hand of Frankenstein's creature begins to move, prompting Frankenstein to shout 'It's alive!'.

The manufactured creature, despite its grotesque form, initially appears to be a simple, innocent creation. Frankenstein welcomes it into his laboratory and asks his creation to sit, which it does. He then opens up the roof, causing the creature to reach out towards the sunlight. Fritz enters with a flaming torch, which frightens the creature. Its fright is mistaken by Frankenstein and Waldman as an attempt to attack them, and it is chained in the dungeon. Thinking that it is not fit for society and will wreak havoc at any chance, they leave the creature locked up, where Fritz antagonizes it with a torch. As Henry and Waldman consider the creature's fate, they hear a shriek from the dungeon. Frankenstein and Waldman find the creature has strangled Fritz. The creature lunges at the two but they escape, locking the creature inside. Realizing that the creature must be destroyed, Henry prepares an injection of a powerful drug and the two conspire to release the creature and inject it as it attacks. When the door is unlocked the creature lunges at Frankenstein as Waldman injects the drug into the creature's back. The creature falls to the floor unconscious.

Henry collapses from exhaustion, and Elizabeth and Henry's father arrive and take him home. Henry is worried about the creature but Waldman reassures him that he will destroy it. Later, Henry is at home, recovered and preparing for his wedding while Waldman examines the creature. As he is preparing to vivisect it, the creature awakens and strangles him. It escapes from the tower and wanders through the landscape. It has a short encounter with a farmer's young daughter, Maria. She is not afraid of him and asks him to play a game with her in which they toss flowers into a lake and watch them float. The creature enjoys the game, but when they run out of flowers he thinks Maria will float as well, so he throws her into the lake where, to his puzzlement, she drowns. Upset by this outcome, the creature runs away.

With preparations for the wedding completed, Henry is serenely happy with Elizabeth. They are to marry as soon as Waldman arrives. Victor rushes in, saying that the Doctor has been found strangled. Henry suspects the creature, who enters Elizabeth's room, causing her to scream. When the searchers arrive, they find Elizabeth unconscious on the bed. The creature has escaped.

Maria's father arrives, carrying his daughter's body. He says she was murdered, and a band of peasants form a search party to capture the creature, and bring it to justice (dead or alive). In order to search the whole country for the creature, they split into three groups: Ludwig leads the first group into the woods, Henry leads the second group into the mountains, and the Burgomaster leads the third group by the lake. During the search, Henry becomes separated from the group and is discovered by the creature, who attacks him. The creature knocks Henry unconscious and carries him off to an old mill. The peasants hear his cries and they regroup to follow. They find the creature has climbed to the top, dragging Henry with him. The creature hurls the scientist to the ground. His fall is broken by the vanes of the windmill, saving his life. Some of the villagers hurry him to his home while the rest of the mob set the windmill ablaze, killing the entrapped creature inside.

At Castle Frankenstein, Frankenstein's father, Baron Frankenstein, celebrates the wedding of his recovered son with a toast to a future grandchild.

Bride of Frankenstein Edit

On a stormy night, Percy Bysshe Shelley (Douglas Walton) and Lord Byron (Gavin Gordon) praise Mary Shelley (Elsa Lanchester) for her story of Frankenstein and his Monster. Reminding them that her intention was to impart a moral lesson, Mary says she has more of the story to tell. The scene shifts to the end of the 1931 Frankenstein.

Villagers gathered around the burning windmill cheer the apparent death of the Monster (Boris Karloff). Their joy is tempered by the realization that Henry Frankenstein (Colin Clive) is also apparently dead. Hans (Reginald Barlow), father of the girl the creature drowned in the previous film, wants to see the Monster's bones. He falls into a flooded pit underneath the mill, where the Monster – having survived the fire – strangles him. Hauling himself from the pit, the Monster casts Hans' wife (Mary Gordon) to her death. He next encounters Minnie (Una O'Connor), who flees in terror.

Henry's body is returned to his fiancée Elizabeth (Valerie Hobson) at his ancestral castle home. Minnie arrives to sound the alarm about the Monster, but her warning goes unheeded. Elizabeth, seeing Henry move, realizes he is still alive. Nursed back to health by Elizabeth, Henry has renounced his creation, but still believes he may be destined to unlock the secret of life and immortality. A hysterical Elizabeth cries that she sees death coming, foreshadowing the arrival of Henry's former mentor, Doctor Septimus Pretorius (Ernest Thesiger). In his rooms, Pretorius shows Henry several homunculi he has created, including a miniature queen, king, archbishop, devil, ballerina, and mermaid. Pretorius wishes to work with Henry to create a mate for the Monster and offers a toast to their venture: "To a new world of gods and monsters!" Upon forcing Henry to help him, Pretorius will grow an artificial brain while Henry gathers the parts for the mate.

The Monster saves a young shepherdess (Anne Darling) from drowning. Her screams upon seeing him alert two hunters, who shoot and injure the creature. The hunters raise a mob that sets out in pursuit. Captured and trussed to a pole, the Monster is hauled to a dungeon and chained. Left alone, he breaks his chains, kills the guards and escapes into the woods.

That night, the Monster encounters a gypsy family and burns his hand in their campfire. Following the sound of a violin playing "Ave Maria", the Monster encounters an old blind hermit (O. P. Heggie) who thanks God for sending him a friend. He teaches the monster words like "friend" and "good" and shares a meal with him. Two lost hunters stumble upon the cottage and recognize the Monster. He attacks them and accidentally burns down the cottage as the hunters lead the hermit away.

Taking refuge from another angry mob in a crypt, the Monster spies Pretorius and his cronies Karl (Dwight Frye) and Ludwig (Ted Billings) breaking open a grave. The henchmen depart as Pretorius stays to enjoy a light supper. The Monster approaches Pretorius, and learns that Pretorius plans to create a mate for him.

Henry and Elizabeth, now married, are visited by Pretorius. He is ready for Henry to do his part in their "supreme collaboration". Henry refuses and Pretorius calls in the Monster who demands Henry's help. Henry again refuses and Pretorius orders the Monster out, secretly signaling him to kidnap Elizabeth. Pretorius guarantees her safe return upon Henry's participation. Henry returns to his tower laboratory where in spite of himself he grows excited over his work. After being assured of Elizabeth's safety, Henry completes the Bride's body.

A storm rages as final preparations are made to bring the Bride to life. Her bandage-wrapped body is raised through the roof. Lightning strikes a kite, sending electricity through the Bride. Henry and Pretorius lower her and realize their success. "She's alive! Alive!" Henry cries. They remove her bandages and help her to stand. "The bride of Frankenstein!" Doctor Pretorius declares.

The Monster comes down the steps after killing Karl on the rooftop and sees his mate (Elsa Lanchester). The excited Monster reaches out to her, asking, "Friend?" The Bride, screaming, rejects him. "She hate me! Like others" the Monster dejectedly says. As Elizabeth races to Henry's side, the Monster rampages through the laboratory. The Monster tells Henry and Elizabeth "Yes! Go! You live!" To Pretorius and the Bride, he says "You stay. We belong dead." While Henry and Elizabeth flee, the Monster sheds a tear and pulls a lever to trigger the destruction of the laboratory and tower.

Son of Frankenstein Edit

Baron Wolf von Frankenstein (Basil Rathbone), son of Henry Frankenstein, relocates his wife Elsa (Josephine Hutchinson) and their young son Peter (Donnie Dunagan) to the family castle. Wolf wants to redeem his father's reputation, but finds that such a feat will be harder than he thought after he encounters hostility from the villagers, who resent him for the destruction his father's monster wreaked years before. Aside from his family, Wolf's only friend is the local policeman Inspector Krogh (Lionel Atwill) who bears an artificial arm, his real arm having been "ripped out by the roots" in an encounter with the Monster as a child.

While investigating his father's castle, Wolf meets Ygor (Bela Lugosi), a demented blacksmith who has survived a hanging for graverobbing and has a deformed neck as a result. Wolf finds the Monster's comatose body in the crypt where his grandfather and father were buried; his father's sarcophagus bears the phrase "Henrich von Frankenstein: Maker of Monsters" written in chalk. He decides to revive the Monster to prove his father was right, and to restore honor to his family. Wolf uses the torch to scratch out the word "Monsters" on the casket and write "Men" beside it. When the Monster (Boris Karloff) is revived, it only responds to Ygor's commands and commits a series of murders; the victims were all jurors at Ygor's trial. Wolf discovers this and confronts Ygor. Wolf shoots Ygor and apparently kills him. The Monster abducts Wolf's son as revenge, but cannot bring himself to kill the child. Krogh and Wolf pursue the Monster to the nearby laboratory, where a struggle ensues, during which the Monster tears out Krogh's false arm. Wolf swings on a rope and knocks the Monster into a molten sulphur pit under the laboratory, saving his son.

Wolf leaves the keys to Frankenstein's Castle to the villagers. The film ends with the village turning out to cheer the Frankenstein family as they leave by train.

Ghost of Frankenstein Edit

The residents of the village of Frankenstein feel they are under a curse and blame all their troubles on Frankenstein's monster. The Mayor allows them to destroy Frankenstein's castle. Ygor finds the monster released from his sulfuric tomb by the explosions. The exposure to the sulfur weakened yet preserved the monster. Ygor and the monster flee the castle, and the monster is struck by a bolt of lightning. Ygor decides to find Ludwig, the second son of Henry Frankenstein, to help the monster regain his strength.

Ludwig Frankenstein is a doctor who, along with his assistants Dr. Kettering and Dr. Theodore Bohmer, has a successful practice in Visaria. Bohmer was formerly Ludwig's teacher but is now his envious assistant. Ygor and the monster arrive in Vasaria, where the monster befriends a young girl, Cloestine Hussman. The monster carries her onto a roof to retrieve her ball, killing two villagers who attempt to intervene. After Cloestine asks the monster to bring her back down, the monster returns the girl to her father Herr Hussman and is immediately captured by police.

The town prosecutor, Erik Ernst, comes to Ludwig and asks him to examine the giant they have captured. Ygor then visits Ludwig and informs him that the giant is the monster. Ygor implores Ludwig to heal the monster's body and brain. Ludwig refuses, but Ygor threatens to reveal Ludwig's ancestry to the villagers.

At the police station, the monster is restrained with chains as a hearing is conducted to investigate the murder of the villagers. When Ludwig denies recognizing the monster, it breaks free in a fit of rage, and is led away by Ygor. Elsa, Ludwig's daughter, finds the Frankenstein journals and learns the story of the monster. She sees Ygor and the monster in the window, and after breaking into Ludwig's laboratory, the monster kills Dr. Kettering. The monster grabs Elsa, but Ludwig is able to subdue him with knockout gas.

Ludwig is examining the monster when it awakens and tries to kill him. Ludwig tranquilizes the monster and then tries to enlist Bohmer's aid in dissecting him. Bohmer refuses, claiming it would be murder. While studying his family's journals, Ludwig is visited by the ghost of his father Henry Frankenstein. The spirit implores him to supply the monster with a good brain. Ludwig calls in Bohmer and Ygor and tells them that he plans to put Dr. Kettering's brain into the monster's skull. Ygor protests and asks Ludwig to use his brain, but Ludwig refuses because of Ygor's sinister nature. Elsa begs Ludwig to stop his experiments, but he chooses to operate on the monster as soon as possible. Ygor tells Bohmer that he should not be subordinate to Ludwig. Ygor promises to help the disgraced doctor if he agrees to put Ygor's brain into the monster.

The police soon arrive at Ludwig's house, searching for the monster. They find the secret room, but Ygor and the monster have fled. The monster abducts Cloestine from her home and returns with her in his arms to Ludwig's chateau. The monster conveys his desire for her brain to be placed in his head. Cloestine does not want to lose her brain, and the monster reluctantly gives her to Elsa. Ludwig then performs the surgery, not knowing that Bohmer has replaced Kettering's brain with Ygor's. In the village, Herr Hussman rouses his neighbors by telling them his daughter has been captured by the monster and that Ludwig is harboring it. Ludwig shows the monster to Erik, but when the monster rises, Ludwig is shocked to hear that it has Ygor's voice.

The villagers storm the chateau and the Ygor-Monster decides to have Bohmer fill the house with gas to kill them. Ludwig tries to stop him, but the Ygor-Monster repels the attack and mortally wounds Ludwig. The Ygor-Monster suddenly goes blind. The wounded Ludwig explains that the blindness is a result of the incompatibility between the blood types of Ygor and the monster. Feeling betrayed, the Ygor-Monster then throws Bohmer onto the apparatus, electrocuting him, and inadvertently sets fire to the chateau. The Ygor-Monster becomes trapped in the burning chateau while Erik and Elsa escape, walking out into the sunrise.

Frankenstein Meets the Wolf Man Edit

Some four years after the events of The Wolf Man and The Ghost of Frankenstein, two men break into the Talbot family crypt to open the grave of Larry Talbot (Lon Chaney, Jr.), seeking valuables buried with him, on the night of a full moon. During the robbery, the thieves remove the wolfsbane buried with Talbot, and he is awakened from death by the full moon shining on his uncovered body. Talbot reflexively grasps the arm of the grave robber with a fur-covered hand, as the cryptkeeper flees.

Talbot is found by police in Cardiff later in the night, with a vicious head wound (administered by his father at the end of The Wolf Man), and taken to a hospital where he is treated by Dr. Mannering (Patric Knowles). Talbot slowly comes to understand his situation, but during the full moon, he transforms into the Wolf Man and kills a police constable. The next morning, Mannering realizes his patient had been roaming about, and tries to reason with him, though unable to accept Talbot's explanation of his curse. Dr. Mannering allows Inspector Owen (Dennis Hoey), to question Talbot who becomes violently irate, then is overcome by orderlies and bound to his bed with leather straps. Not believing his story of being a werewolf, the doctor and detective travel to the village of Llanwelly to investigate Talbot and his story. While they are away, Talbot escapes from the hospital, by biting through the restraints with his teeth. Seeking a cure for the curse that causes him to transform into a werewolf with every full moon, Talbot leaves Britain and seeks the gypsy woman Maleva (Maria Ouspenskaya), who has hearsay knowledge of Dr. Frankenstein (Ludwig Frankenstein, as the action is returning to the Ghost of Frankenstein locale) and opines he may able to help Talbot. Together they travel to the village of Vasaria, where Talbot hopes to find the notes of Dr. Frankenstein in the remains of the his estate, and permanently end his own life through scientific means. The townsfolk want no part of them or their desire to meet with the deceased Frankenstein and rudely order them to leave.

An upset Talbot transforms into the Wolf Man and howls madly, causing the villagers of Vasaria to raise a mob to chase him down. Fleeing toward the ruins of the Frankenstein manse, Talbot falls through the burned-out flooring and into the frozen cellars below. Talbot recovers from his animal state, and wanders around, discovering Frankenstein's Monster (ironically portrayed by Lon Chaney Jr. in the preceding film)]], but actually stuntman Gil Perkins) frozen in ice and thaws him out with a fire. Finding that the Monster is unable to locate the notes of the long-dead doctor, Talbot seeks out Baroness Elsa Frankenstein (Ilona Massey) the daughter of Ludwig, posing as a potential buyer of the estate, hoping she knows their hiding place. She declines to assist Talbot, but the pair are invited to the "Festival of the New Wine" by the Burgomeister (Lionel Atwill).

During the festival, a performance of the life-affirming folk song Faro-la Faro-Li enrages Talbot as Dr. Mannering arrives. The doctor, having followed him across Europe, converses with Talbot to persuade him to return to Wales before he has another spell. Talbot refuses to go with Mannering, and the Monster crashes the festival. With the Monster revealed, Elsa and Mannering agree to help the villagers rid themselves of the Frankenstein curse forever. The following morning, the couple, with Maleva in tow, meet with Talbot and the Monster at the ruins. Mannering is instantly fascinated by the Monster scientifically, and the Baroness gives the notes to Talbot and the doctor. Mannering studies the notes and learns how to drain all life from both Talbot and the Monster, believing the laboratory can be repaired for the task.

In the meantime, the villagers are dismayed to see crates of instruments arriving for Dr. Mannering to enable the experiment and become restless, knowing nothing of the doings at the ruins. Vazec, the innkeeper details a plan to destroy the dam overlooking the old estate with dynamite and drown all within, ending their troubles in one blow. The Burgomeister dismisses the idea as nothing but a drunken notion, but Vazec is determined and puts his plan into action.

Unfortunately, Dr. Mannering's scientific curiosity to see the Monster at full strength overwhelms his logic, and to Elsa's horror he decides to fully revive it. The experiment coincides on the night of a full moon, and Talbot transforms yet again as the Monster regains his strength (and eyesight); both escape their restraints.

The Monster begins to carry Elsa away, but the Wolf Man attacks him, and she escapes from the castle with Mannering. The Wolf Man and the Monster then engage in a fight until they are both swept away in the flood that results when Vazec dynamites the dam

House of Dracula Edit

Count Dracula (Carradine) arrives at the castle home of Dr. Franz Edlemann (Onslow Stevens). The Count, who introduces himself as "Baron Latos", explains that he has come to Visaria to find a cure for his vampirism. Dr. Edlemann agrees to help. Together with his assistants, Milizia (Martha O'Driscoll) and the hunchbacked Nina (Jane Adams), he has been working on a mysterious plant, the clavaria formosa, whose spores have the ability to reshape bone. Edlemann explains that he thinks vampirism can be cured by a series of blood transfusions. Dracula agrees to this, and Edlemann uses his own blood for the transfusions. Dracula has his coffin placed in the castle basement.

That night, Lawrence Talbot (Chaney Jr.) arrives at the castle. He demands to see Dr. Edlemann about a cure for his lycanthropy. Talbot is asked to wait. Knowing that the moon is rising, Talbot has himself incarcerated by the police. A crowd of curious villagers gathers outside the police station, led by the suspicious Steinmuhl (Skelton Knaggs). Inspector Holtz (Lionel Atwill) asks Edlemann to see Talbot, and as the full moon rises, they both witness his transformation into the Wolfman. Edlemann and Milizia have him transferred to the castle the next morning. Edlemann tells him that he believes that Talbot's transformations are not triggered by the moonlight, but by pressure on the brain. He believes he can relieve the pressure, but Talbot must wait for him to gather more mold from his spores. Despondent by the thought of becoming the Wolfman again, Talbot says he wants to kill himself and jumps into the ocean. He ends up in a cave below the castle.

Edlemann searches for Talbot and finds that he survived the fall, but has turned into the Wolfman. The Wolfman attacks, but suddenly returns to his human form as the moon goes behind the clouds. In the cave, they find the catatonic Frankenstein monster (Strange), still clutching the skeleton of Dr. Niemann. Humidity in the cave is perfect for propagating the clavaria formosa, and a natural tunnel in the cave connects to a basement of the castle. Dr. Edlemann takes the monster back to his lab, but considers it too dangerous to revive him.

Dracula tries to seduce Milizia and make her a vampire, but Milizia wards him off with a cross. Edlemann interrupts to explain that he has found strange antibodies in the Count's blood, requiring another transfusion. Nina begins shadowing Milizia, who is weakened by Dracula's presence; Nina notices that the Count casts no reflection in a mirror. She warns Edlemann of the vampire's danger to Milizia. Edlemann prepares a transfusion that will destroy the vampire. During the procedure, Dracula uses his hypnotic powers to put Edlemann and Nina to sleep; he then reverses the flow of the transfusion, sending his own blood into the Doctor's veins. When they awake, Dracula is carrying Milizia away. They revive Talbot and force Dracula away with a cross. Dracula returns to his coffin as the sun is beginning to rise. Edlemann follows him and drags the open coffin into the sunlight, destroying Dracula.

Edlemann begins to react to Dracula's blood, and becomes evil. He no longer casts a reflection in a mirror. Falling unconscious, he sees strange visions of himself performing unspeakable acts. When he awakens, his face has changed to reflect his evil nature just like in his vision, then he returns to his normal self.

Edlemann performs the operation on Talbot. Afterwards, he transforms again into his evil self and brutally murders his gardener. When the townspeople discover the body, they chase Edlemann, believing him to be Talbot. They follow him to the castle, where Holtz and Steinmuhl interrogate Talbot and Edlemann. Steinmuhl is convinced that Edlemann is the murderer, and assembles a mob to execute him.

Talbot is cured by the operation, but Edlemann again turns into his evil self. He revives the Frankenstein monster, but the monster is very weak. Nina is horrified by Edlemann's transformation, and Edlemann breaks her neck and tosses her body into the cave. Holtz and Steinmuhl lead the townspeople to the castle. The police attack the Frankenstein monster, but the monster subdues them. Edlemann kills Holtz by accidental electrocution. Talbot shoots Edlemann dead. Talbot traps the Frankenstein monster under fallen shelving. A fire breaks out, and the townspeople flee the burning castle. The burning roof collapses on the Frankenstein monster.

House of Frankenstein Edit

Dr. Gustav Niemann (Boris Karloff) escapes from prison along with his hunchbacked assistant Daniel (J. Carrol Naish), for whom he promises to create a new, beautiful body. The two murder Professor Lampini (George Zucco), a traveling showman, and take over his horror exhibit. To exact revenge on Bürgermeister Hussman (Sig Ruman), who had put him in prison, Niemann revives Count Dracula (John Carradine). Dracula seduces Hussmann' granddaughter-in-law Rita (Anne Gwynne) and kills Hussmann himself, but in a subsequent chase, Niemann disposes of Dracula's coffin, causing the vampire to perish in the sunlight.

Niemann and Daniel move on to the flooded ruins of Castle Frankenstein, where they find the bodies of Frankenstein's monster (Glenn Strange) and Lawrence Talbot, the Wolf Man (Lon Chaney Jr.), preserved in the frozen castle. Nieman thaws out the two and promises to find Talbot a cure for the curse. However, he is more interested in reviving the monster and exacting revenge on two traitorous former associates than in keeping his promises. Talbot transforms into a werewolf and kills a man, sending the villagers into a panic.

Niemann and Daniel save a gypsy girl named Ilonka (Elena Verdugo), and Daniel falls in love with her; it is unrequited, however, as Ilonka falls in love with Talbot. Daniel tells Ilonka that Talbot is a werewolf, but she is undeterred, and promises Talbot that she will help him.

Events reach a crisis point when Niemann revives the monster and Talbot again turns into a werewolf. The werewolf attacks and fatally wounds Illonka, but she manages to shoot and kill Talbot with a silver bullet before she dies. Daniel blames Niemann and turns on him. The monster intervenes, throws Daniel out of the window, and carries the half-conscious Niemann outside, where the villagers chase them into the marshes. There, both the monster and Niemann drown in quicksand.

Abbott and Costello Meet Frankenstein Edit

Lawrence Talbot (Lon Chaney Jr.) makes an urgent phone call from London to a Florida railway station where Chick Young (Bud Abbott) and Wilbur Grey (Lou Costello) work as baggage clerks. Talbot tries to impart to Wilbur the danger of a shipment due to arrive for "McDougal's House Of Horrors", a local wax museum. The crates purportedly contain the remains of Count Dracula (Béla Lugosi) and the Frankenstein monster (Glenn Strange). However, before Wilbur can understand, a full moon rises and Talbot transforms into a werewolf. He proceeds to destroy his hotel room while Wilbur is on the line. Wilbur thinks the call is a prank and hangs up. Meanwhile, the museum owner, McDougal (Frank Ferguson), has arrived to claim the shipments. When Wilbur badly mishandles the crates, McDougal demands that the boys deliver them to his museum so his insurance agent can inspect them.

Chick and Wilbur deliver the crates after hours. They open the first one and find Dracula's coffin. When Chick leaves the room to retrieve the second crate, Wilbur reads aloud the Dracula legend printed on an exhibit card. The coffin slowly creaks open. Wilbur is so frightened that his attempts to call Chick result in helpless sputtering. Before Chick returns with the second crate, Dracula climbs unnoticed out of his coffin and hides in the shadows. Wilbur claims that the coffin opened, but Chick shows him that it is in fact empty. While the boys open the second crate containing the Monster, Chick leaves the room to greet McDougal and the insurance agent. Dracula now hypnotizes Wilbur and reanimates the Monster. They both leave, and by the time McDougal, the insurance agent, and Chick enter, both crates are empty. McDougal accuses the boys of theft and has them arrested.

That night, Dr. Sandra Mornay (Lenore Aubert) welcomes Dracula and the Monster to her island castle. Sandra, a gifted surgeon who has studied Dr. Frankenstein's notebooks, has seduced Wilbur as part of Dracula's plan to replace the Monster's brutish brain with a more pliable one--Wilbur's.

Wilbur and Chick are bailed out of jail. They assume that Sandra posted bond, but Joan Raymond (Jane Randolph), an undercover investigator for the insurance company, did so. Joan also feigns love for Wilbur, hoping he will lead her to the missing "exhibits". Wilbur invites Joan to a masquerade ball that evening. Meanwhile, Lawrence Talbot has tracked Dracula and the Monster from Europe and has taken the apartment across the hall from Wilbur and Chick. Talbot asks Chick and Wilbur to help him find and destroy Dracula and the Monster. Wilbur believes, but Chick remains skeptical.

That night Wilbur, Chick and Joan go to Sandra's castle to pick her up for the ball. Wilbur answers a telephone call from Talbot, who informs them that they are in fact in the "House of Dracula". Wilbur reluctantly agrees to search the castle with Chick, and soon stumbles upon a basement staircase that leads to a boat and dock. Chick insists they search for Dracula and the Monster to prove to Wilbur that they do not really exist. Behind a revolving door, Wilbur experiences a few close calls with the monsters; whenever he tries to get Chick's attention, the monsters have disappeared. Meanwhile, Joan discovers Dr. Frankenstein's notebook in Sandra's desk, and Sandra finds Joan's insurance company employee ID in her purse.

As the men and women prepare to leave for the ball, a suavely dressed Dr. Lejos (a.k.a. Dracula) introduces himself to Joan and the boys. Also working at the castle is the naive Prof. Stevens (Charles Bradstreet), who questions some of the specialized equipment that has arrived. After Wilbur admits that he was in the basement, Sandra feigns a headache and tells Wilbur and the others that they will have to go to the ball without her. In private, Sandra admits to Dracula that Stevens's suspicions, Joan's credentials, and Wilbur's snooping in the basement have made her nervous enough to put the experiment on hold. Dracula asserts his will by hypnotizing her and biting her in the neck. (In a continuity error, Dracula's reflection is visible in a mirror. Vampires do not have a reflection, as stated in Dracula (1931).)

Everyone is now at the masquerade ball. Talbot arrives and confronts Dr. Lejos, who is in costume as Dracula. Lejos easily deflects Talbot's accusations and takes Joan to the dance floor. Sandra lures Wilbur to a quiet spot in the woods and attempts to bite him, but Chick and Larry approach and she flees. While Talbot, Chick and Wilbur search for Joan, Talbot transforms into the Wolf Man and stalks Wilbur. Wilbur escapes, but the Wolf Man attacks McDougal, who is also at the ball. Since Chick's costume includes a wolf mask, McDougal accuses Chick of attacking him out of revenge. Chick escapes, and witnesses Dracula hypnotizing Wilbur. Chick is also hypnotized and rendered helpless while Dracula and Sandra bring Wilbur and Joan back to the castle. The next morning, Chick and Talbot, both fugitives, meet up in the bayou. Talbot confesses to Chick that he is indeed the Wolf Man. Chick explains that Dracula has taken Wilbur and Joan to the island, and they agree to work together to rescue them.

Wilbur is held in a pillory in the cellar. Sandra explains her plan to transplant his brain into the Monster. When she and Dracula leave him to prepare the Monster for the operation, Chick and Talbot sneak in set Wilbur and Stevens free. Dracula and Sandra return to the cellar and find Wilbur missing; Dracula easily recalls Wilbur, and he soon finds himself strapped to an operating table in the lab. The Monster is on an adjacent table, receiving electric shocks. As Sandra brings a scalpel to Wilbur's forehead, Talbot and Chick burst in. Talbot pulls Sandra away from Wilbur, and Chick unintentionally knocks her out while fending off Dracula with a chair. Chick flees the lab pursued by Dracula. Talbot is about to untie Wilbur when he once again transforms into the Wolf Man. Dracula returns to the lab and engages in a brief tug of war with the Wolf Man over Wilbur's gurney. Dracula flees and the Wolf Man gives chase. Chick returns to untie Wilbur just as the Monster, now at full power, breaks his restraints and climbs off his gurney. Sandra attempts to command him, but the Monster picks her up and tosses her out the lab window to her death. Chick and Wilbur escape the lab and run from room to room with the Monster following them.

Dracula, while fighting with the Wolf Man, attempts to escape by transforming into a bat. The Wolf Man leaps, catches the bat, and tumbles off a balcony onto the rocks below. Presumably, both are killed. Joan abruptly wakes from her trance, and is rescued by Stevens. The boys run out of the castle to the pier, with the Monster still in pursuit. They climb into a small row boat while Stevens and Joan arrive and set the pier ablaze. The Monster wheels around into the flames, succumbing as the pier collapses into the water.

Wilbur scolds Chick for not believing him. Chick insists that now that all the monsters are dead, "there's nobody to scare us anymore." They suddenly hear a disembodied voice (provided by an uncredited Vincent Price) and see a cigarette floating in the air. The voice says, "Oh, that's too bad. I was hoping to get in on the excitement. Allow me to introduce myself—I'm the Invisible Man!" The boys jump out of the boat and swim away while the Invisible Man laughs.
