An alluring new French dress is released, dubbed "Nude at Midnight," and various women try to use the sexy garment to gain leverage with the men in their personal and professional lives. Marion (Marilyn Maxwell) dons the dress and arranges a date with her hubby's employer, hoping to grease the man into giving her spouse a promotion. Working girl Betty (Paulette Goddard) wears it to win the heart of her own boss, and ambitious Gogo (Eva Gabor) uses it in an effort to seduce a wealthy maharajah.
