In this silent film, two American soldiers fight to escape the Germans while squabbling over a beautiful harem girl during World War I.

Private Phelps and Sergeant McGaffney, who are constantly scrapping until they meet a common foe, are taken prisoners by Germans during the war, and failing many attempts to escape, they succeed in slipping out in Arab disguise. Finding themselves on a steamer bound for Jaffa, McGaffney, Phelps, and the ship's captain discover themselves rivals for Mirza, an Arab girl of rank. Young Phelps makes progress with her by sign language, even to the point of making her remove her veil. In Jaffa, a spying servant informs Shevket, her fiancé, of her acquaintance with the American, and her father, the emir, plots to imprison them, but they are saved by the American consul. The emir makes the soldiers knights so that Phelps can fight a duel with Shevket; but in a series of escapades, the boys foil their enemies and abscond with the girl.
