Margot Sherwood Merrick, the editor of a fashion magazine, has invented a fictitious husband, Tony Merrick, because she thinks that men see that women in business as fair game unless they are wearing a ring on the third finger of their left hand. Margot's ruse backfires, however, when she meets Jeff Thompson, an opinionated artist with a disdain for New York, who falls in love with her. Upon discovering Margot's deception, an angry Jeff decides to get even by pretending to be her estranged Tony Merrick. After Jeff, as Tony, moves into Margot's home with her sister Vicky and father, an exasperated Margot asks Philip Booth, the magazine's attorney who is in love with her, for advice. Philip convinces Jeff that he must marry and then divorce Margot so that she will be free to marry Philip. Jeff and Margot travel to Niagara Falls for the wedding, where they meet some old friends from Jeff's home town in Ohio. Deciding to even the score, Margot pretends to be Jeff's crude bride from Brooklyn. Margot then returns to New York, planning to fly to Reno to file a divorce. Her old friend August Winkel, however, a photographer for the magazine, realizes that she is in love with Jeff and convinces her to accompany him on the train home to Ohio so that they can work out a property settlement before the divorce. Jeff, Margot and Philip board the train to complete the agreement, but the next morning when the train stops at Jeff's home town, Jeff and Margot leave as husband and wife, much to Philip's dismay.
