England 1944. In the shadow of the war raging in Europe, Tom and Anna meet by chance. He is an American pilot on a 72-hour pass and she is a secretary, trapped in a life going nowhere. Surprised by each other, they begin a passionate affair.
Their happiness does not last. Shot down over Europe, wounded and in hiding, Tom has no way of telling Anna he is alive. And Anna, left waiting in England, has no way of finding out. How can she know that Tom is struggling to return to her? Or that the thought of her is all that keeps him going on the long journey home? In a world where promises are hard to keep, all she can do is hope. Until she discovers her mother is keeping secrets, and then it is a race against time.
