October 1941. Despite the hardships of life during wartime, Bobby Bancroft has never been happier. Engaged to her airman sweetheart Charlie, living in the beautiful Dales village of Silverdale and gainfully employed at The Tyke magazine, her life seems to be going exactly the way she always hoped it would. As the festive season approaches, Bobby is recruited to help produce a Christmas pantomime for the evacuee children billeted in the village. The project introduces her to some new friends, including a handsome Canadian, Flying Officer Ernie King, and her friend Topsy's upper-crust cousin Archie Sumner. However, fresh troubles arise when Charlie discovers his RAF training is to be cut short and he must prepare to join the fight imminently. What's more, his upcoming leave has been cancelled, leaving him to spend a lonely Christmas in his barracks. Can a miracle bring Charlie and Bobby together for Christmas?
