When an executed original of a secret treaty between England and France, known as the French Treaty, is stolen from the country estate of Lord Halifax, Scotland Yard asks Joanna, Dr. John Watson, Jr., and Dr. John Watson, Sr. to use their keen detective skills to participate in the hunt for the missing treaty.
