Elizabeth Lane is a single New Yorker, employed as a food writer. Her articles about her fictitious Connecticut farm, husband, and baby are admired by housewives across the country. Her publisher, Alexander Yardley, is unaware of the charade and insists that Elizabeth host a Christmas dinner for returning war hero Jefferson Jones, who read all of her recipes while in the hospital and is so fond of her that his nurse, Mary Lee, wrote a letter to the publisher. Facing a career-ending scandal, not only for herself but for her editor, Dudley Beecham, Lane is forced to comply. In desperation, Elizabeth agrees to marry her friend, John Sloan, who has a farm in Connecticut. She also enlists the help of her uncle, chef Felix Bassenak, who has been providing her with the recipes for her articles.
At Sloan’s farm on Christmas Eve, Elizabeth meets Norah, the housekeeper, as well as a neighbor’s baby whom they pretend is their baby. Elizabeth and John plan to be married immediately by Judge Crowthers, but the ceremony is interrupted when Jefferson arrives early. Elizabeth is smitten and it is love at first sight.
The judge returns on Christmas morning, but the ceremony is postponed when a different neighbor’s baby is presented instead of the one from the day before. The household is alarmed when Felix claims that the baby has swallowed his watch. After the judge leaves, Uncle Felix admits to Elizabeth that he had lied about the watch to stop the wedding. While the household attends a local dance, the baby’s real mother arrives to pick up her baby. Alexander witnesses her leaving with the child and assumes someone is kidnapping the baby. Elizabeth and Jefferson spend the night in jail, mistakenly charged with stealing a neighbor’s horse and sleigh, and return to the farm early the next morning. Alexander chastises Elizabeth for being out all night and accuses her of neglecting her child. Elizabeth finally confesses all. Furious, Alexander fires her.
Jefferson’s fiancée, Mary Lee, arrives unexpectedly. Dejected, Elizabeth retires to pack her things and leave the farm. Felix learns that Mary Lee has already married someone else and must break the engagement. He entices Alexander into the kitchen with the smell of cooking kidneys. He fabricates a story about a competing magazine’s attempts to hire Elizabeth, and Alexander decides to hire her back. Felix tells Jefferson that he is free to pursue Elizabeth. Elizabeth’s packing is interrupted, first by Alexander, and then by Jefferson. After teasing her that he is a cad who woos married women, Jefferson reveals the truth. The couple kiss and plan to marry.
