From dealing with a wandering grandmother to witnessing the deaths of her friends, she is determined not to let the war beat her down. She joins the ARP and eventually becomes a local heroine, but behind the smiling face hides a private pain she could never speak of. Despite the toils of war, the only thing Nell really lives for are the letters from abroad and the hope of a better tomorrow.
