After Canada declares war against Germany in World War II, she joins the British Women's Auxiliary Air Force as an aerial photographic interpreter. Working with intelligence officers at RAF Medmenham in England, Rose spies on the enemy from the sky. When her commanding officer, Gideon Fowler, sets his sights on Rose both professionally and personally, her prospects look bright. But can he be trusted? As she becomes increasingly disillusioned by the destruction of war and Gideon's affections, tragedy strikes, and Rose's world falls apart. Rose struggles to rebuild her shattered life and finds that victory ultimately lies within herself.
