The seduction plans of novelist Malcolm Niles go awry when actress Vivian Herford brings along her mother to a candlelight dinner in his New York apartment. When they talk of marriage, Malcolm decides to make a tour promoting his new book, and in a small southern town meets Nancy Briggs at an autographing session at the local bookstore. Nancy is getting married that night, but her fiancé, working in New York, doesn't come back for the wedding, so her family gives her the fare to go to New York to find him. At the same time, Malcolm gets a wire from his publisher and friend, Robert Hanson, telling him to come home because Vivian has left town. Traveling to New York on the same train, Nancy proves to be a pest who Malcolm hopes to avoid once they arrive, but when Nancy can't find her fiancé, she goes to Malcolm, since he's the only one she knows in the city. He is about to kick her out when Vivian returns, so he uses Nancy as an excuse to get rid of Vivian. In the ensuing days, Nancy cooks and cleans for both Malcolm and Robert, who lives next door. Trouble begins when Robert falls in love with Nancy and Malcolm finds that he is jealous.
