Gary Cooper (Professor Jesper) is a nuclear scientist who is sent on an espionage assignment into Switzerland to discover and report back what progress the Nazis have made in developing an atomic bomb. It's World War II and the race is on to blow each other up. He is told that respected scientist Helen Thimig (Katarin Lodor) is to be his point of contact but his assignment turns into a rescue mission on meeting her. When this fails, he switches his focus to Italy where he links up with the Italian Underground movement in order to rescue Vladimir Sokoloff (Polda), another super-brain scientist.
The film reminded me of a James Bond style spy story. The cast are all OK and there are plenty of sequences that propel the plot forwards, although the film loses it's pace a bit with the romantic section between Cooper and Resistance fighter Lilli Palmer (Gina), which slows things down for about 20 minutes.
As regards the plot, I'm not sure it makes sense. Jesper is sent to find out information and report back, but he ends up in the front-line as a spy with a gun who has to fight and defend himself and is involved in a kidnapping plot. Totally unreal but it really doesn't matter. It's an enjoyable film with a collection of memorable sequences, eg, the French Resistance at the beginning, the scene when Cooper confronts undercover Gestapo agent Marjorie Hoshelle (Ann Dawson), the Italian Resistance and the episode in the truck, and the fight scene between Cooper and Marc Lawrence (Luigi).
