In 1942, British pilot Jimmy Briggs crashes his aeroplane in occupied France and immediately finds himself on the run from the Nazis. He meets a young girl, Nina, a part-Jewish agent with important information, and vows to get her back to Britain. He is helped by another agent, code-named Vincent, and pursued across France by S.S. Officer Lutzig, and the ambivalent Abwehr Sgt. Gratz.
