A Soviet blockade has put 2.2 million civilians under siege. To avoid war, Britain and the U.S. launch an airlift.
Former B-17 captain J.B. Baronowsky and Kit Moran, a former Lancaster skipper, once risked their lives to deliver high explosives to Hitler’s capital. They are about to start delivering flour, medicine and children’s shoes instead.
While the men fly supplies into the besieged city, an ex-ATA woman pilot and an American nurse work together to transport sick, injured and malnourished children out.
Then bad weather closes in, and all flights are grounded. It begins to look like the Russians might win.
