Hugh Williams, Ralph Richardson and Deborah Kerr star in this British wartime drama. As Hitler invades Poland in 1939, British journalist Colin Metcalfe (Williams) is appointed as Norway's new foreign correspondent. During a sea voyage of his new home, his boat comes under fire from a German U-boat despite the country's neutrality. But when he reports the attack to the British embassy they disbelieve him and - to add insult to injury - remove him from his post. When German forces later invade Norway, Metcalfe returns, determined to uncover what is going on and to stop the Nazis in their tracks.
