Miss Armistead is a nurse in the surgical division of a hospital. She is being courted by two men, Dr. Joe Trask, the chief resident, and Dr. Mort Baker, an established and very successful surgeon. Everyone in the division is taking bets on her choice. Most assume she will choose Baker, the wealthier, more powerful doctor.
Then Miss Armistead develops appendicitis and requires emergency surgery. Joe Trask is on duty and has to begin the operation before Baker arrives, but experiences a terrible crisis of confidence, becoming helpless with fear. Baker arrives and completes the operation.
Everyone assumes that this will clinch Baker’s victory, but when Joe tells her how he was unable to operate on her, Miss Armistead takes this inability to see her as just another patient to be proof of the depth of his love for her, and agrees to marry him.
