On the night of his wife's surprise party in honor of their twentieth wedding anniversary, eccentric department store owner Henry Butler becomes so immersed in the arrangement of a mannequin for a window display that he completely loses track of time. As Henry wrestles with the blonde dummy, one of the party guests, Clara Drake, drives past the store and sees Henry embracing a blond figure. Midway through his arrangement, Henry drops and breaks the mannequin, thus making him even later for dinner. As the guests at the party await his arrival, Clara begins spreading the story of Henry's love affair with a blond model. Meanwhile, Henry, on his way to get the dummy repaired, is stopped by the police for suspicion of murder and, by the time he is released, the party has ended. When Henry finally arrives home with the model's slipper in his pocket, his wife Effie, encouraged by her troublemaking friend, Grace Norman, files for a divorce. Grace introduces Effie to her smooth-talking divorce lawyer, Gilbert Wayne, who sends Gooch the bodyguard to watch his new client. Because neither Henry nor Effie will leave the house, Effie's niece Jane comes to chaperone her aunt, and Bob Grant arrives as Henry's keeper. Bob and Jane try to effect a reconciliation between the two and almost succeed when, smelling a fat fee, Wayne brings in his girlfriend, Nan Blake, to impersonate the blond who lost the slipper. Bob and Jane trick Nan into exposing Wayne's divorce racket, however, and all ends happily when the police arrest Wayne and Henry introduces Effie to his dummy.
