Famous screen star Cherry Chester is called back home to New York by her stern grandmother Lucy Van Steedan, who insists that Cherry marry her dimwitted cousin Horace Van Steedan, despite Cherry's protests. At the same time, famous adventurer/writer Anthony Amberton is in New York signing copies of his new book. Cherry and Anthony are scornful of each other, although they are not acquainted. When Anthony is overcome by the smell of Cherry's signature perfume in a department store, he runs out, chased by a mob of adoring fans, and leaps into Cherry's horse-drawn carriage. Unaware of each other's identity, they are instantly attracted and talk familiarly without introducing themselves. Anthony hurriedly leaves, but deposits a card in Cherry's hand as an invitation to his favorite winter hotel in Moonsocket, New Hampshire. Lucy arranges an ocean cruise to Europe where she intends to have Cherry and Horace marry, but Cherry disappears at the docks and travels to Moonsocket. There, she and Anthony introduce themselves by their real names, Sarah Brown and John Smith, and fall in love. They get married on a whim, but on their wedding night, Cherry uses some of her perfume, making Anthony unbearably ill. Ignorant of the reason behind his strange behavior, Cherry becomes irate and returns to New York, where she arranges to meet Horace. As he is an old acquaintance of Horace, Anthony attends his engagement party and discovers that Cherry is Horace's fiancée. Upon revealing their celebrity identities to each other, Cherry and Anthony have a knockdown fight. Cherry then leaves with Horace to catch a flight for California, where they intend to marry. After Anthony reveals to Lucy his marriage to Cherry, she has Horace temporarily arrested under false pretenses, thereby allowing Anthony time to catch up with Cherry at the airport, where they reconcile.
