"It's 1939, Europe is on the verge of war and Princess Margaret begins a diary to record her wartime experiences. But more exciting than blackouts, evacuees, and doodlebugs is her sister Elizabeth's blossoming romance with Prince Philip of Greece. Margaret dreams of a royal wedding, but Philip is sent to serve in the navy and Elizabeth longs to join the army. Will there be a fairy tale ending?"
