Starring Paul Newman, Julie Andrews

Attending a nuclear conference, American scientist Michael Armstrong suddenly leaves Stockholm and flies to East Berlin. Refusing to believe that he has defected to the Communists, his fiancee and colleague, Sarah Sherman, follows him across the Iron Curtain. She does not realise that her actions will endanger Armstrong, who is, in fact, an American agent.
Hitchcock assembled a strong international cast to give credibility to this tense thriller, shot on location throughout Europe.
