Leslie Howard updated his 1934 role as Baroness Orczy's "Scarlet Pimpernel" in this classy wartime drama. As Professor Horatio Smith, he portrays the archetypal English book-worm professor ostensibly looking for evidence of a German Aryan civilisation, but actually smuggling out POWs from under the nose of an excellently portrayed General von Graum (Francis L. Sullivan). Mary Morris plays von Graum's secret mole in a charming fashion and helps this film convey an overall more sophisticated counterfoil to the evil Nazi agenda.
