Nurse Edith Cavell (1939)

English nurse Edith Cavell is matron in a small private hospital in German-occupied Brussels during WWI. After the son of a recently deceased patient escapes from a German prisoner-of-war camp, Cavell helps him reach Holland and safety. This leads to Cavell, a local noblewoman, the grandmother of the escaped prisoner-of-war, and others to form an organization to help Belgian, French, English and other soldiers escape as well. Eventually the Germans become aware of what's happening and take action.
