Ashton Kirk is a wealthy and scholarly young man who solves mysteries that have the police puzzled. Stella Morse asks Kirk to find out who is threatening her uncle, Dr. Morse. Morse has a copy of a secret treaty between Russia and the United States that was made during the Russo-Japanese War. When the Doctor is murdered Kirk takes on the case. Japanese spies have been trying to purloin the treaty to ruin relations between its country and America. Kirk manages to get the treaty himself and prevents a war from breaking out.
