Classic wartime drama. When John Franklin (David Beames) crash lands his Wellington bomber in occupied France at the height of the Second World War, he is concerned for the safety of his crew and worried about his own badly injured arm. His crew escapes, but the family of a mill owner risk their lives to hide Franklin in their home until he regains his health. During the following balmy summer months, the pilot's situation is further complicated by his feelings for Francoise (Cecile Paoli), the daughter of the house. As German patrols move in, his only chance of survival is to flee from France.
