Lieut. Jack Bradley, 16th U.S. Cavalry, on furlough, a guest at Esplanade Hotel, Fortress Monroe, becomes engaged to Margaret Lane, a New York society girl, who requests him to keep their engagement a secret. One day, while playing tennis, Jack throws his coat on a bench on which Margaret is sitting, and in picking it up she finds a photograph of a beautiful girl which had fallen from one of the pockets. Margaret, who is of a jealous disposition, becomes enraged and making a package of the photo and her engagement ring, sends them to Jack without an explanation. Jack, mystified, tries to see Margaret, but she snubs him at his every approach. Receiving orders to rejoin his regiment, he is forced to leave without learning the cause of his dismissal. Margaret returns home and receives the attentions of Col. Richard Everett, who is so persistent in his love-making he induces her to become his bride, although Margaret has no love for her soldier husband.
