Harold Mark marries Thora after treating her injured grandfather, then migrates to New York City with his young wife to study surgery. While Harold devotes himself to his studies and to social problems, Thora seeks expression with Greenwich Village bohemians and falls prey to the flattery of sculptor Monsieur Duparc, who convinces her that she is neglected by her husband. After the Marks separate, Harold becomes chief surgeon of a state hospital, and Thora spends a year as the guest of Duparc's aunt. On his way to persuade Harold to divorce Thora, Duparc is injured in an automobile accident. Harold unselfishly performs lifesaving surgery on Duparc, while a crazed patient sets fire to the hospital. Afterward, Harold returns to Thora's country home. She follows and they are reconciled.
