On the eve of Pearl Harbor, Lucy Stanhope, the granddaughter of an earl, is living a life of pampered luxury in Singapore until one reckless act will change her life forever. Exiled to England to stay with an aunt she barely remembers, Lucy never dreamed that she would be one of the last people to escape Singapore before war engulfs the entire island. Then she meets Bill, a young evacuee sent to the country to escape the Blitz, and in a moment of weakness, Lucy agrees to help him find his mother in London. The unlikely runaways take off on a seemingly simple journey across the country, but her world becomes even more complicated when she is reunited with an invalided soldier she knew in Singapore.
