Neilan, an architect, young and ambitious, having graduated with honors, procures a position as assistant in the city architect's office. Although hearts are willing, his love affair with Toddles seems hopeless owing to Toddles' sense of duty as a sister to Pauline, an invalid. Neilan calls upon Toddles and presses her for a definite answer to his proposal. Toddles refuses, telling him she cannot marry while her sister lives. Pauline suffers a relapse, due to her mental agitation, and the doctor advises Toddles that the only hope of prolonging Pauline's life is the South American climate.
