Set in post-war 1946-47, Foyle (Kitchen) and his loyal friend Sam (Weeks) find themselves adjusting to a new era of secrets, intelligence and security as their worlds shift into those of MI5. With one war ended, a new one is looming as the iron curtain falls across Europe.

During his inquiry, Foyle learns that his former driver, Sam, has been working for one of the possible suspects. Could she be involved?
