Young swinging patrons of an exclusive dating service are turning up, dead of old age. The police don't believe they are the same persons, but Kolchak investigates and discovers that the head of the dating service is actually Helen of Troy, who sacrifices perfect young victims to Hecate, her patron goddess, in return for eternal youth and beauty. The fact that Helen is unaware one of the victims had a glass eye and lied about it on their form proves vital to Kolchak when he accidentally dons one of the rings that lets Helen sacrifice her victims in the appropriate manner.
