In the late 1800s, the enigmatic Dracula makes his way to London, disguising himself as an American businessman eager to introduce contemporary science to the Victorian era. His fascination lies particularly with the emerging technology of electricity, which offers the advantage of illuminating the night—a boon for someone who shuns daylight. However, Dracula’s journey has a deeper motive: he seeks vengeance against those who condemned him to eternal life many years ago. His scheme unfolds smoothly until he becomes enamored with a woman who seems to be the reincarnation of his deceased spouse.
