Inspired by the runaway success of the British and American Gothic horror films of the sixties, Toho brought the vampiric tropes of the Dracula legend to Japanese screens with The Vampire Doll (Legacy of Dracula), Lake of Dracula, and Evil of Dracula - three spookily effective cult classics collectively known as 'The Bloodthirsty Trilogy'. In 'The Vampire Doll', a young man goes missing after visiting his girlfriend's isolated country home. His sister and her boyfriend trace him to the creepy mansion, but their search becomes perilous when they uncover a gruesome family history. 'Lake of Dracula' begins with a young girl suffering a terrifying nightmare of a vampire with blazing golden eyes. Eighteen years later, the dream is revealed to be a hellish prophecy when a strange package containing an empty coffin mysteriously turns up at a nearby lake. In 'Evil of Dracula', a professor takes up a new post at an all-girls school only to discover the school's principal conceals a dark secret and the pupils are in grave danger.
