With the Third Reich disintegrating, several members of the German army are defecting to the Americans and offering their services as spies. US officer Gary Merrill trusts none of these last-minute converts, but German prisoner Oskar Werner seems to be sincere. Werner insists that by helping the Americans, he is saving Germany from destruction. Merrill sends Werner behind enemy lines for counter-espionage with an American officer (Richard Basehart), who still isn't convinced that the German expatriate means what he says. At several critical junctures, it seems as though Werner had been lying about his mission, but at the last moment he saves Basehart's life at the cost of his own...but was this act of bravery intentional? A thoughtful World War II drama, Decision Before Dawn was filmed on location in Europe. Watch for a young and sickly-looking Klaus Kinski as an overeager defector.~ Hal Erickson, All Movie Guide
