A heart-wrenching farewell scene between an explorer and his beloved: This photo from 1961 has been haunting archivist Abby Gordon's mind. She begins to trace the tragic story of the love couple, even though unhappy love, following the failure of her own marriage, is the last thing Abby wants to think about right now. Ultimately, she makes the image the centerpiece of a planned exhibition and finds herself facing a surprising visitor at the opening: Rosamund Bailey, an icon of journalism and the woman in the photo.
