End of the World

When NASA scientist Andrew Boran (Kirk Scott) intercepts some strange alien transmissions in space, his initial jubilation and euphoria is cut short by the eventual realization that these alien radio signals are coming from nowhere else, but from Earth. Unable to come to terms with this discovery, Boran and his wife, Sylvia (Sue Lyon) take it upon themselves to investigate the source of these signals. And that brings them to a convent, which they soon realize has been taken over by aliens. Masquerading in human forms, the alien Zindar (Christopher Lee) divulges how he and his people, from the planet Utopia, plan to destroy Earth, a hotbed of diseases and calamity, for the sake of the entire galaxy.
