When a mother dies of heart failure in a doctor's office, the physician--feeling somewhat guilty because he couldn't save her--takes an interest in the woman's young daughter, and makes her his ward, but his fiancé doesn't particularly like it. After he returns from a three-year engagement in Europe, the doctor discovers that his ward is now a beautiful, full-grown woman, and finds himself falling for her--even though she's engaged to his fiancé's brother.
Two brothers, Jack and Tom, are in love with the same woman, Molly. While the two brothers go off to war and Molly does her part in the effort, Tom believes that Rose is waiting for him, while in fact, she loves Jack and only turned to Tom on the rebound.
