Plot.
1925: an American archaeologist, Desmond Jordan moves to Africa, seeking the "Speaking Mountain". This brings him into the middle of the Sahara desert, where he meets some deserters from the French Foreign Legion. Jordan escapes with Orso (Bear) from a siege by Ryker, a lieutenant of the battalion, and moves towards the mountain.
Ryker and El Hallem, head of local tribes, pursue Jordan, who has gone blind approaching the mountain. The lieutenant gives vent to his violence, murdering some locals and sparing only their queen, Anthea. Later she cures Jordan's blindness and, together with El Hallem (redeemed), helps the archeologist to defeat Ryker.
Eventually, Jordan helps Anthea and Orso discover the secret of the mountain.
