Plot Summary

Toward the end of World War II, the allied secret service receives a partial message indicating that the Germans are researching nuclear energy to build atomic bombs. In Midwestern University, the scientist Alvah Jesper is called up by the Office of Strategic Services (OSS) to meet his former colleague Dr. Katerin Lodor in Switzerland and bring her to North America. However, his mission fails and Dr. Lodor is killed by the Nazis but first she informs that Alvah's acquaintance Dr. Giovanni Polda is working for the Nazis in Italy. Dr. Jesper travels to Italy and with the support of the Italian partisans leaded by Pinkie and Gina, he has a meeting with Dr. Polda that is under the surveillance of the Gestapo. The scientist tells him that his daughter Maria had been abducted by the Gestapo and Alvah makes a deal with Dr. Polda, promising to release Maria first and bringing them to North America. While Pinkie travels to rescue Maria, Alvah stays with Gina and they fall in love for each other. Written by Claudio Carvalho, Rio de Janeiro, Brazil

Trivia According to the book 'The Films of World War II' by Joe Morella, Edward Z. Epstein and John Griggs (1973), "This film is significant because of its attitude and treatment of the subject of nuclear weapons . . . In the version seen by the public the film ends with [Gary Cooper] completing his mission, rescuing the Italian scientist and accompanying him back to the Allies. He leaves Lilli Palmer behind him but it is implied he will return for her after the war. Director [Fritz Lang\ has said that in the original ending the scientist dies on the plane and the British and U.S. secret service men must further pursue the Nazis. From a photo left by the scientist they surmise that the Nazis have an installation in Bavaria. They find the site has been abandoned and there is dialogue to this effect: 'Probably the plant is in Argentina now--or somewhere.' Lang has stated that the final fade-out had Cooper walking out of the abandoned cave seeing an American soldier. The sun is shining, birds are singing and Cooper says, 'This is the Year One of the Atomic Age and God help us if we think we can keep this secret from the world, and keep it for ourselves.' According to the director, the entire fourth reel was cut and probably doesn't exist any longer. He assumes that Warners cut his ending because it was too soon after the bombs had been dropped on Hiroshima and Nagasaki." See more »
