Robert Donat is the innocent man who gets caught up in an espionage plot and is suspected of murdering a woman in his Londan flat. He then goes up to Scotland to try and clear his name where he is forced to team up with Madeleine Carroll. This is a good version of the story and an early example of Alfred Hitchcock's work who gets good performances from both Robert Donat and Madeleine Carroll.
