La châtelaine du Liban

In 1934, Captain Cassard of the Camel Corps in Palmyra accidentally witnesses Oriental spies committing murder and becomes a target. He is taken prisoner and his incarceration drives him mad. He is possessed by a vengeful desire to betray his country and fanatical love for the Lady of Liban, a mysterious fortune teller. When he is released, broke and distraught, he sells military secrets to an antiquities dealer to raise money. His commanding officer, deeply suspicious of him, orders a court-martial. Cassard, in desperation, seeks the help of Neguib El Tarab and his men-friends, desert nomads, for a stolen cache of gold. In finding it he atones for his past and returns to his military duties, and his fiancee.
