Plot

Six girls have been found murdered in the apartment of famed Russian occultist Karl Raymarseivich Raymar and the police cannot explain it. When Raymar's body was lifted onto a stretcher, bolts of electricity shot out from his fingers. His estranged daughter Olivia McKenna (Melissa Newman) and her husband Allan (Adam West) are unaware of this until they meet Samuel Dockstader (Donald Hotton), a feature writer for The World of the Occult; as a friend of Raymar, Dockstader explains that Raymar was a psychic vampire who gained great powers of telekinesis by kidnapping young girls, terrorizing them, and feeding off the bioenergy they produced. Allan does not believe him, but Dockstader shows Olivia a set of photographs to demonstrate how bioenergy works and gives her an audiotape that outlines his findings, which convinces Olivia to believe him.
