The Nude Vampire

In a strange laboratory, three men in weird masks take the blood of a naked young woman in a hood. Another woman in an orange négligée is wandering the streets and is followed by a group of people wearing animal heads. The woman comes across a man named Pierre who tries to help her, but the masked men corner them and shoot the woman; Pierre escapes unharmed. The masked men take the woman into a building, and Pierre follows. Guests then arrive for some sort of party, but Pierre can't get into the building. Another scene reveals his father is behind it.
