A Son of the Desert (1928)

Helen Dobson, an art student traveling in Arabia with her father, wishes to paint the portrait of Sheik Hammid Zayad, but the Arab explains that the custom of his country does not permit it. Against the advice of her father and Steve Kinard, a Texas cowboy employed to buy horses, Helen accepts the sheik's invitation to visit his camp, where he promises to show her treasures to satisfy her interest in the picturesque. Helen's horse returns riderless. Suspecting that the sheik is holding her against her will, Steve and Mr. Dobson, after several adventures, rescue Helen.
