A Hollwood producer Jerry Lydecker, played by genre actor John Saxon most famous for the 'Nightmare on Elm Street' films, buys one of Jessica's book and tranforms it into an entirely different movie. So she flies out to L.A. to confront him.

Basically, he bought it for the title. Jessica is not happy with the way the story has been changed in the film. Her name and reputation are stake...Jessica tells him she going to 'do whatever it takes to stop this picture from being made.' right in front of his secretary...that's going to come back and bight her in the butt.
Jessica finds the body of Jerry Lydecker on the graveyard set and of course is now a suspect in his murder.
John Astin aka Gomez Addams is the director of the movie, Ross Hayley. He tells Lt. Hernandez that pretty much everyone wanted Lydecker dead.
Lt. Hernandez 'volunteers' Jessica to go tell the 'leading lady', Eve Crystal (Melissa Sue Anderson...aka Mary Ingalls in 'The Little House on the Prairie') that Lydecker has been murdered...she finds her at his beach house, drunk.
The film company decide to they want to continue with making the movie. Ross Hayley is now the producer and director of 'The Corpse Dances at Midnight'.
Lt. Hernandez dramatically arrests Jessica on the set of the movie...but he knows that she'll find the real killer. But she's been barred from the lot as a 'disruptive influence'..so how is she going to solve the murder!
Somehow, she gets to watch some of the rushes and sees something that peaks her interest. Crystal Eve and her co-star Scott Bennett are an 'item'.

Jessica goes to the Wardrobe Department and talks to the head Wardrobe Mistress, Elinor, played by screen legend Virginia Mayo!
She goes to check Crystal Eve's dressing room when Hayley runs out and knocks her over. Lt. Hernandez arrests him for Lydecker's murder and when he pats him down he finds the button that Jessica was looking for earlier.
Jessica throws a party as she's about to head back to Cabot Cove...but the party is a classic mystery move...she's going to confront the real murderer!
She does a toast to Ross Hayley 'Wrongfully accused of murder.' and then everybody suddenly leaves accept for Crystal.
Ross did take the button from the murder scene but only to protect Crystal...she's the one who murdered Lydecker because he was going to fire her lover Scott Bennett.
Jessica figured it out because 'real drinkers' don't mix whiskey and diet cola...Crystal is a diabetic and can't drink...she was faking it.
