Two college co-eds and fans of Karole work for a caterer at the Con, serving people they admire as well as some they could live without. Peter Branson, a young TV star becomes enamored of Heather at one of the events. Harry Jackson, a literary agent notorious for seducing young aspiring writers leaves with a young woman. Heather and Toni run to Karole with the story and when she goes upstairs the girl is unconscious and Harry is dead, his mouth and throat stuffed with condoms.

Harry's body is discovered by Stella and Paula, but it is Karole who is accused of the murder, due to her long-standing feud with Jackson. The professors team up with the co-eds, and assisted by a journalist and a police detective, they investigate the murder. The outcome is a shocking one, the murderer a surprising discovery, who manages to create a dramatic scene at the Con ball before she is cornered.

Harry Jackson was murdered because he was indiscriminately spreading AIDS throughout the fantasy community -- his murderer has been infected as was one of her dear friends.
