Prisoners in Petticoats is a misleadingly innocuous title for this girls-behind-bars melodrama. It all begins when innocent cocktail pianist Joan Grey (Valentine Perkins) is implicated in a crime committed by her gangster boss (Anthony Caruso). Rather than reveal her true identity, thereby humiliating her highly respected father (Alex Gerry), Joan tells the police nothing, and is sent to prison as a consequence. Oddly, the most exploitable angle of this film, i.e. Joan's misadventures behind bars, is downplayed in the second half of the film, which is primarily devoted to the investigation conducted by special investigator Mark Hampton (Robert Rockwell). Veteran musical comedy performer Queenie Smith steals the show as an elderly convict.
