 English nurse Edith Cavell is matron in a small private hospital in German-occupied Brussels during WWI. When the son of a recently deceased patient escapes from a German prisoner-of-war camp, Cavell aids him to 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.
