Although told that Hassan should never leave the island of El Hierro, there is no explanation. Then Arab slavers appear, first to capture natives as slaves, but instead kidnap Hassan and take him to an Arab sheik to be killed. The true reason becomes exposed why the sheik wants him dead as Francois, Col. Santana, and Hassan's best friend, Filipe, race across an ocean of water and sand to rescue him. However, the elements seem to be against them. As the usurper sheik gloats over his victory, the long silent Lions of el Bayadh begin to roar.
