Bafta-nominated Virginia McKenna gives an understated but well-pitched performance as Violette Szabo, a glamorous young woman whose life in London is barely affected by the Second World War until she meets and marries a French officer.
But he is soon killed in action, and she finds herself drawn into espionage work, risking her life in occupied France as a British spy.
Made by the same team of director Lewis Gilbert and co-writer Vernon Harris that brought the Douglas Bader biopic Reach for the Sky (1956) to the screen, this is another well-crafted biographical drama inspired by real-life heroism beyond the call of duty.
The supporting cast is pretty good, too, and includes an all-too-rare big-screen appearance from theatre giant Paul Scofield.
