In Hollywood, Bill Martin (Jack Oakie) plays a detective on film. He gets into a feud with the real police. Studio publicist Mary Strand (Ann Sothern) isn't happy with him either although she does really like him. He starts getting creepy fan letters from "The Poison Pen". With a killer targeting him, he and Mary go to amateur sleuth Professor Herman (Eduardo Ciannelli) for help.
Bill Martin is somewhat a self-obsessed boob. I don't hate him but I don't love him either. With a bit of well placed charms, he could be a passable romantic lead. Oakie needs some work. Sothern is doing all the work in the relationship. The hair piece is the funniest gag but it's the Lieutenant. There is still some fun to be had.
