Audrey Totter plays an FBI clerk who is pressed into more active duties by her bosses Cesar Romero and George Brent. Audrey's job is to uncover the criminal past of above-reproach politician Raymond Greenleaf. A pre-Perry Mason Raymond Burr plays a hulking hoodlum who suspects that Audrey is working for the feds. The comedians Tommy Noonan and Peter Marshall (yes, that Peter Marshall) shows up as guest stars on a TV program being watched by Audrey in the villain's lair. Overladen with up-to-date crime-busting technology, FBI Girl was based on a story by Rupert Hughes, the uncle of Howard R. Hughes.
