In 1940, on the eve of the United States' entrance into World War II, Iris James, the postmistress of Franklin, a small town on Cape Cod, does the unthinkable: she doesn't deliver a letter. In London, American radio gal Frankie Bard is working with Edward R. Murrow, reporting on the blitz. One night in a bomb shelter, she meets a doctor from Cape Cod with a letter in his pocket. She vows to deliver the letter when she returns from Germany and France where she is to report on war refugees desperately trying to escape. The residents of Franklin think the war can't touch them; but as Frankie's radio broadcasts air, some know that the war is indeed coming. And when Frankie arrives at their doorstep, the two stories collide in a way no one could have foreseen.
