Representatives of the big European nations meet and draw up a secret treaty affecting the Far Eastern countries. In order to safeguard the document, the Minister of Foreign Affairs places it in a safe guarded by ten automatic pistols, so arranged that anyone tampering with the combination will receive the full discharge of the pistols. If this secret treaty is adopted it will seriously interfere with the careers of the Mongolian residents of the capital city. Accordingly, Prince Frederick poses as a nobleman in order to steal the treaty and destroy it. At a reception, the spy meets Banker Newell’s daughter, whom he learns is engaged to Minister Carr, the custodian of the treaty. While at the card table, Banker Newell receives a letter of blackmail, which he drops in his excitement. The spy secures this letter and finds evidence of a crime committed by Banker Newell years before. With this proof, he forces the banker’s daughter to pledge her aid to his cause, and arranges with her to enter Minister Can’s home and inveigle him into opening the safe. That night the spy struggles with Carr’s fiancée, who has repented of her promise to betray her intended husband, in Minister Carr’s room. As be tampers with the combination of the safe, the door swings open, the ten automatic pistols discharge their contents. Although fatally wounded, the spy seizes the treaty, and dying, reaches the Mongolic Club, where his death occurs. In Minister Carr’s home, the banker’s daughter is dead, a victim of political intrigues.
