That most English of actors, James Mason, stars as a French intelligence officer in this exciting World War II adventure, which was made while the war was in full swing! Parachuting into occupied France along with fellow agents Roland Culver, Michael Wilding and Hugh Williams, Mason embarks on a suicide mission to determine the strength of the German defence forces - a mission that takes them to the heart of Nazi headquarters. But with half the German army on their trail, will they be able to survive long enough to get their vital information to the British troops? A tense behind-enemy lines story, 'Secret Mission' has all the classic elements from the golden age of British War films, with non-stop action and intrigue, and plenty of self-sacrificing heroics as Mason and his team blow up munitions dumps and shoot it out with those villainous goose-steppers. It's a mission that no fan of great British War films would want to miss out on!
