The Desert Song (1929)

French General Birabeau has been sent to Morocco to root out and destroy the Riffs, a band of Arab rebels, who threaten the safety of the French outpost in the Moroccan desert. Their dashing, daredevil leader is the mysterious "Red Shadow". Margot Bonvalet, a lovely, sassy French girl, is soon to be married at the fort to Birabeau's right-hand man, Captain Fontaine. Birabeau's son Pierre, in reality the Red Shadow, loves Margot, but pretends to be a milksop to preserve his secret identity. Margot tells Pierre that she secretly yearns to be swept into the arms of some bold, dashing sheik, perhaps even the Red Shadow himself. Pierre, as the Red Shadow, kidnaps Margot and declares his love for her.
