After spending a year in a London brothel, Fanny Hill returns to the castle of Lady Chatterly, her former employer. The castle has since been let to a lascivious old doctor, who is trying to bring to life the man he has created. Fanny is taken back to work as a servant girl, devoting herself once again to lovemaking. Inadvertently, she triggers the electrical connections which bring the monster to life. Upon awakening, he sees Fanny and falls in love with her. Though the doctor is angry with Fanny, he cannot send her away because his monster insists on following her everywhere. She is forced to keep the monster in her bedroom. When another young maid visits Fanny's room to make lesbian advances, the monster thinks his mistress is being hurt, and he comes to her rescue. The maid's screams upset the monster, who runs berserk through the countryside and is finally cornered in a barn. When the townspeople set the barn on fire, the doctor's life work is destroyed, and Fanny must return to the road once more.
