The Secret of Dr. Kildare

Dr. Leonard Gillespie, racing against time in his battle with melanoma, is about to start an important research project at Blair General Hospital to improve the use of a Sulfa drug, Sulfapyridine, as a cure for pneumonia. Dr. James Kildare poses as an old friend of the Messenger family in order to observe Nancy's sudden personality changes that occur in his daughter Nancy. Gillespie's assistant forces Gillespie to take a rest as a patient, forcing him to work full-time on the Messenger case.
