Very stiff-upper-lip WWII drama. In 1943, Stefan (Rennie) and his friend Tadek (Knight) are members of the Polish resistance. They allow themselves to be captured and taken to a labor camp in order to find out about the Nazis' V-1 rocket program. They manage to get word to the allies, who destroy the camp, but the Nazis regroup and the next move is to get a completed V-1 rocket, smuggle it out of the country, and send it to Britain. Utilizes footage of actual air raids.
