At a reception given for the vacationing Prince Zarl of Zorania, secretly the emissary of Zorania set on negotiating a treaty with the United States, Geoffrey Wynne, apparently a society dandy, but in reality a secret service agent, meets the prince. During the reception, Wynne is summoned to Washington where he learns that the treaty has been stolen and is being held for $15,000,000 ransom. Discovering that one of the thieves is an Italian named Farnelli, Wynne enlists the aid of his fiancée, Irene Mitchell, in apprehending the thief. Irene meets the Italian who offers to accompany her to New York. En route, Wynne overtakes them, chloroforms Farnelli and rips off his disguise to reveal Prince Zarl. Zarl then admits that he has stolen the treaty in order to cover his gambling debts.
