Based on true facts, it is a WorldWar II spy story. The chief of British Secret Service (MI6) Stuart Menzies sends his best agent, Andrew Bond, to a difficult mission in nazi Germany. He must locate and help evade a distinguished electronics professor who has been captured by the Germans and possesses some secrets on electronic warfare. If not, Bond has to kill the professor. Bond locates the professor in Stalag Luft II and they take part in the great escape (true event). Then they travel through Germany being chased by a deadly German Abwehr agent. He will find some unexpected help from a beautiful German girl. Will they be able to reach neutral Switzerland?
