Frankie Ryan works as a page boy at a radio station located in Hollywood. His friend Jeff works in the same place, but as a porter. Their real dream is to perform as radio comedians on the air, with their own show. Unfortunately they haven't convinced anyone about their great sense of humor yet. When they try to help the station receptionist, Anne Mason, by setting up a false audition for the position as singer, they are almost fired for their antics.
The station has financial problems related to their current moody singer Rita Wilson, and try to find a way to get rid of her. Their prayers are heard when Rita is shot and killed during a blackout when she is rehearsing for a broadcast.
Police detectives Marty Phillips and Delaney arrive at the scene, and even though they haven't found the murder weapon, they start suspecting a wannabe cowboy singer, Tex Barton, who tried to slip out the back door after the shooting. He was in the audience when Rita was rehearsing before the blackout.
