The three bachelors live together in loneliness. Each night they return to their rooms and exchange solitary greetings. One evening one of their number reads in the newspaper of a poor woman who is unable to support her little daughter and wishes to have someone adopt her. The bachelors visit the poverty-stricken woman and come to an agreement with her to educate her daughter and to provide for her maintenance in the best fashion. The child, Rosemary, grows up to be a handsome young woman with every advantage of environment and surrounding. The bachelors lavish money on her and give her everything she happens to mention. The bachelors' housekeeper dies and the girl mourns her loss greatly. The bachelors fear that the girl takes her loss too much to heart and come to the conclusion that what she really needs to make her happy is a husband. All three decide to propose to her, hoping that she will chose one of their number. Rosemary is much amused by the three proposals but tells each one of her suitors that she loves, but not any more than she does the others. She promises, however, that the one who will bring her the most appropriate gift on her eighteenth birthday will stand highest in her affections. Acting upon her hint the three bachelors scour the town seeking appropriate presents, Robert decides that a beautiful imported gown which he sees at a fashion show would be the most acceptable gift of all and has the package sent home to Rosemary. Henry steps into a jewelers and buys Rosemary an elaborate diamond necklace. Vincent, however, comes to the conclusion that Rosemary does not seek a gift of only material value and when he overhears her making an inquiry about her mother, whom she does not remember, Vincent decides to find the old lady and to bring her to live with her now grown-up daughter. Accordingly he follows several clues and at last learns where Rosemary's mother is living. He finds the old lady in a squalid tenement but with everything about her neat and clean. Telling her that he is about to give back her child, Vincent induces her to visit a fashionable dressmaker and secures an apartment for her in a much better neighborhood. On Rosemary's birthday Robert opens up the box containing the expensive imported gown. Rosemary is enraptured with it and kisses the fortunate Robert enthusiastically. Then Henry presents her with a diamond necklace and Rosemary again demonstrates her affection and gratitude upon the donor. All then look expectantly at Vincent to see what he has to give. Vincent leads a kindly-faced wrinkled up old lady into the room, and when she has removed her veil, presents her to her daughter. An affecting meeting between mother and daughter follows and the other two bachelors, Robert and Henry, take Vincent aside and congratulate him upon his happy choice of a gift. All then gaily make merry to celebrate the engagement between Vincent and Rosemary and the return of Rosemary's mother to become the housekeeper for the two disappointed bachelors.
