A British nurse on holiday in Germany just prior to the second World War meets a German officer. Their relationship develops and they intend to get married. Unfortunately, the second World War intervenes.
Both are determined to find each other after the war. The girl, Elizabeth, searches for him with the help of a group of American army personnel.
The German officer, Carl, evades capture by the British army in Italy. The British army wants to interrogate him about his services in the German army, both before the war and during the war.
Carl is helped in this evasion by the men in his unit and eventually reaches Germany, his home.
He goes looking for Elizabeth, whom he knows is with the British army medical services.
The interrogation group in the British army assume he will make for his home, so they search for him in that part of Germany. During the course of their search, their man accidently discovers a group of war criminals trying to escape from Germany and is held prisoner.
Carl, at the request of the occupation authorities, helps to bring the group to justice.
