Little Boy Lost

American war correspondent Bill Wainwright (played by Crosby) was stationed in Paris during World War II. His wife was murdered by the Nazis for participating in the French Resistance and his son went missing during a bombing raid. The war is over and the grieving widower has returned to Paris to find his lost little boy. He finds a sad and confused boy, Jean, who does bear a resemblance to Lisa Garret, and believes he might be his son. The Mother Superior insists that the boy is his, but he is skeptical.
