Conventional and slick spy-thriller set during wartime from Fritz Lang at his best. However , Warner Bros reedited the movie into an usual spy melodrama with some action and intrigue . It deals with a scientific enlisted by the secret service and undertaking dangerous adventures throughout Europe . During the last years of WW2 the US learn that the Nazis are investigating an atomic power so the OSS (organization strategic services) asks for help to University Professor Alvah Jasper (Gary Cooper), an American scientist leading the way to atomic bomb development in the USA . They assign him to go to Europe to meet Dr. Polda (Vladimir Sokoloff), an atomic scientist being kidnapped by the Nazis and he is helping them to build the bomb . As Jesper working for the OSS must bring him to the United States, but he first must meet up with his old professor from college Dr. Katerin Lodor (Helen Thimig) who explains him that Polda is in Italy . Then there happens a shockingly casual execution . Later on , Jasper must go to Italy in search of the scientist. In Italy he is accompanied by a group of Italian guerrilla fighters led by a brave American (Robert Alda) and a valiant resistance fighter named Gina (Lilly Palmer). After that , Jasper has a brutal fight (Marc Lawrence) against a Nazi in an alley . And of course Jesper gets the girl and both of whom fall in love for each other.
Interesting espionage film about the dangers of the atomic age with an intrepid physicist who becomes into secret agent working for the O.S.S . Good performance of Cooper as scientist who spend most of the time trotting round Germany , Switzerland and Italy ensuring the Germans don't obtain the atomic bomb . An attractive Lilly Palmer steals the show as sensible female fighter Gina , someone with whom Cooper forms an enjoyable bond in part because she brings out him sensitive qualities . Considered talent involved at the movie as the classic musician Max Steiner who composes a fine score and atmospheric cinematography in black and white by Sol Polito . The version filmed by Fritz Lang was considerably more strong and exciting carrying on to suggest that German scientific has discovered the secret of atomic bomb and escaped with it to Argentina , then Warner Bros got into the act and cut it .The film belong to the Lang's trilogy about Nazi time along with ¨Man hunt¨and ¨Hangmen also die¨. Lang directed masterfully all kind of genres as Noir cinema as ¨Big heat , Scarlet Street and Beyond a reasonable doubt¨ , Epic as ¨Nibelungs¨, suspense as ¨Secret beyond the door, Clash by night¨ and Western as ¨Rancho Notorious and Return of Frank James ¨ .This standard espionage drama with some good and thrilling moments will appeal to Gary Cooper fans .
