"Fleeing a threatened Hindu uprising, Major Crespin and his wife, accompanied by Dr. Traherne, travel by airplane to a distant settlement. The Rajah of Rukh makes them his prisoner-guests when the airplane crashes in his kingdom. He informs the three that they will be killed in retaliation for the approaching execution by the British of his three brothers. Crespin and Traherne bribe the butler to send an appeal for help over the wireless, but he betrays them and loses his life. Crespin gets the message through before the rajah shoots him. British aviators arrive in time to save Traherne and Mrs. Crespin. " --AFI catalog, 1921-1930 (description of film version of play).
