Struggling actor Simon witnesses a murder; he didn't see the killer, but that doesn't stop him from claiming that he did in order to get his name into the papers. Sure enough, the murderer targets him as his next victim. Our hero is temporarily rescued by Jeanne, a fellow aspiring actress who has always had a crush on him.
