While addressing a forum of doctors, Sister Kenny is asked whether she remembers the final paragraph of the oath she took to become a registered nurse, and she recounts that paragraph. The real Sister Kenny received no formal nursing training and was not a registered nurse. She enlisted as a nurse in the army in WWI backed by a letter from a doctor stating she had experience working in a bush hospital and was given the title Sister by the Army.
During the medical director's opening remarks the shot of the audience makes a sudden upwards movement, as if someone bumped against the camera.
