The second part of the Bloodthirsty trilogy — three unrelated Toho-produced vampire movies all directed by Michio Yamamoto — Lake of Dracula shares the Hammer-inspired look of the other two films, looking as gorgeous as only Technicolor-hued skies can make happen. It transplants the gothic feel of British horror squarely into teh Far East with style.
When she was five, Akiko had a nightmare of losing her dog inside a crumbling mansion until she watched a vampire (Shin Kishida, Godzilla vs. Mechagodzilla) drain the blood of a woman. Now an adult, she finds herself back in the grip of that very same vampire, as he arrives in a white coffin, fully prepared to finally claim her.
He starts by taking her friend Kusaku and sister Natsuko as his thralls. As Doctor Takashi Saki has become involved in the case, he saves her as her sister expires in the sunlight of a beach, begging for her corpse to be burned so that she may never return. However, they take her to the morgue where she rises again from the dead, now a full vampire ready to help her new master take her sister once and for all.
If you watched this in Japan, the vampires all disintegrate at the end of this movie. When it was edited for American television, they just fade away.
