Noah Praetorius (Cary Grant) is a physician who cares for patients as human beings and not just bodies. His unorthodox methods are being challenged by Dr. Elwell (Hume Cronyn), who wishes to discredit Praetorius by exposing the secrets of his past. While Elwell investigates, Praetorius cares for a pregnant, unwed student (Jeanne Crain), who on learning of her condition, tries to commit suicide.
In order to give her hope, Praetorius tells the student that he was mistaken about her pregnancy and eventually marries her. In the conclusion, Praetorius reveals to a committee his secret life, which includes the historical questionable necessity of procuring his own cadaver for anatomy study, and wins the day.
