Plot
During World War II, American war correspondent John Davis leaves France for safer London with his wife, Nora, who is pregnant. John wants her to go back home to Connecticut, but she decides to stay on by his side. John is worn down by the war, and Nora has her doubts about his conviction as a reporter.
During The Blitz, John is walking around London in the rubble, moved when discovering a desperate young boy. As he returns home, he learns that his wife has been hurt in the bombings and taken to hospital.
It turns out Nora has lost the baby and is permanently injured, meaning that she will never be able to bear another child. Nora is devastated when she hears the news about her condition.
It takes months for Nora to recover; and, when she does, John tries to put her on a flight home to the United States. She agrees; but John's colleague, Herbert V. Allison, tries to convince her to stay on and fight to get over the ill fate that has befallen her. Despite this, she goes home.
John continues his work writing about war orphans. He meets with the director of the orphanage, Trudy Strauss, and starts caring for the children. He also meets Peter, the boy he saw during The Blitz, who has been mute since he arrived at the orphanage.
John gives Peter a toy he found after The Blitz, which causes the boy to see him as a father figure. Another child, Margaret, comes to the orphanage after being in foster care. She has a bomb casing in a chain around her neck. She has to learn to cry for her dead parents.
At tea time, Peter comes around and starts communicating with the other children. Both Peter and Margaret open up to John in the evening and want him to help them. Later, when bombers fly over the orphanage, John helps calm the children.
London is bombed again during the night; and John and Allison go around looking for stories to write, when they encounter a woman carrying a dead child. John, increasingly upset, is inspired to write stories. Back at the orphanage, Peter and Margaret are to meet their prospective parents. John agrees to accompany them; but they cling to him, even though the potential adopters are very nice.
Via cable, John asks Nora if he can adopt the two children and bring them back with him. Nora's mother answers that Nora is ill but "certain will want children". Nora had a breakdown after receiving his telegram but recovers and writes to confirm she wants him and a home and children, "two, four, ten, bring them".
It turns out the flight from London to Portugal is full. John tries to negotiate with the passengers not to use their full baggage allowance, but it doesn't work. John is allowed to bring only one child and is advised to let the children perform an IQ test to determine which to bring with him. Margaret scores higher, and John must return Peter to foster care. Heartbroken, John still goes to the airport with Margaret; but, when John is about to board the plane, one of the other passengers has given up her baggage allowance to make room for Peter.
Later, after a long trip, John and the children arrive by ship to the port in New York, watching the shimmering lights of the city in the distance. Nora comes to meet them on the ship. There is an air raid alarm, but Nora tells the children that, once the war is over, they will never have to worry that the lights in the city will be turned off.
