 Two people have been murdered in Clayton by a mysterious killer using a blow-gun. Socialite club-leader Phoebe Witherspoon (Virginia Sale) comments that "the town needs another Ma Pilkington, the best police chief the town ever had", and the town s newspaper editor, Henry Wright (Donald MacBride) sends reporter Breezy (William Gargan) to find the late Ma Pilkington s daughter, Jane "Pilky" Pilkington (Joan Davis.) She is given the job of tracking down the killer and policeman Mulligan (Leon Errol) is assigned to assist her. But after two more unsolved murders, Wright buys "Pilky" a ticket back to Horsetrot, the town in which they found her, and summons a chicago detective (Ian Keith) to take over the case. "Pilky" is depressed by this turn of events and more so when she learns that Breezy is engaged to Maybelle (Vivian Austin), an actress. Mulligan is also fired. The killer strikes again by killing stage producer Tommy-Gun Tucker (Milburn Stone) and the Chicago detective decides to go back to the safe confines of the Windy City, leaving "Pilky" again in charge. She sees Maybelle take a note out of Tucker s pocket during the investigation. She filches the note and, through it, tracks down the killer as being town coroner Dr. Bleaker (Paul Stanton), who was mixed up in some shady deals with Tucker and Maybelle. Mulligan is re-instated and "Pilky" remains in Clayton as the police chief.
