O Grande Segredo

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 (Gary Cooper) is called up by the Office of Strategic Services (OSS) to meet his former colleague Dr. Katerin Lodor (Helen Thimig) 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 (Vladimir Sokoloff) is working for the Nazis in Italy. Dr. Jesper travels to Italy and with the support of the Italian partisans leaded by Pinkie (Robert Alda) and Gina (Lilli Palmer), 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.

"Cloak and Dagger" is a suspenseful and full of action romance in times of war. The enjoyable story has good moments of tension but it is only a reasonable work of Fritz Lang. Gary Cooper's character seems to be a skilled and well-trained agent and not a scientist in many moments and Lili Palmer performs a strong female character in one of her first works. My vote is seven.
