Perry is at TV station "KGGY" to be interviewed but thanks to the interference of main anchor-person Brett Huston the interview is pulled. Mostly everybody hates Brett as Brett knows all the station workers secrets. He has also written a memo insulting all of the main station players - Vic St. John - the station manager, Twyla Cooper - the producer, Chuck Gilmore - the sports reporter, Gary Slate - the weatherman, Cassie Woodfield - the reporter and Gillian Pope. Brett is shot dead with Gillian's gun and therefore is arrested for the crime. Gillian calls in Perry, Della and Ken to investigate. As Della and Perry set out to solve the mystery, Ken gets close to Cassie but she is a suspect and when it appears that somebody is trying to kill her, the mystery deepens..
Unfortunately the movie Perry Mason: The Case of the Ruthless Reporter is not yet available on Disney Plus.
