A British intelligence agent transporting secret documents to America realizes German spies are following him and slips a microfilm copy of the plans to unsuspecting socialite Nancy Partridge (Marjorie Lord). After the agent disappears, the British Home Office sends Sherlock Holmes (Basil Rathbone) and his partner, Dr. Watson (Nigel Bruce), to Washington, D.C., to solve the mystery. When the agent is murdered, Holmes deduces Nancy's involvement and races against the Germans to find her.
