In search of a maid, Mrs. Cook, an aristocratic and extremely proud society woman, goes to an employment agency and hires Luna, fat, awkward and straight from Sweden. The new maid creates quite a stir in the staid and fashionable home of Mrs. Cook. While capering about in her room above, she brings down the ceiling. Mrs. Cook saves her from being discharged and then calls up the plasterer, whose name is John Haines, a widower, and the father of Bert, the chauffeur, in love with Marie Cook, their daughter. John fixes the ceiling, and on his return home finds a note from his son saying he is going to be married and suggests his father follow his example. John tells the news to Luna, proposes to her, and without a second's hesitation, she accepts him. That night, Luna sees Marie and Bert elope and, in her excitement, makes a racket which is heard by Mr. and Mrs. Cook. Mr. Cook thinks it is burglars and holds Luna up with a gun. They find a note left by the elopers, telling of their intention, which adds to the confusion. Next day the elopers return for forgiveness, but Mrs. Cook refuses it. Suddenly Luna bursts in and introduces her husband, John Haines. Mrs. Cook looks disgusted and takes no interest in the matter until John takes his son, Bert, to his fatherly heart. Marie's parents then realize that Haines is Bert's father, and he and Luna are relatives of the Cooks by marriage. Luna is overjoyed, brings wine to celebrate the grand occasion, slaps Mrs. Cook heartily on the back, winding up by seizing Mr. and Mrs. Cook in one huge embrace and giving them both a resounding kiss on the cheek.
