A fabulous land of green pastures is protected from invasion by the mysterious Valley of the Thundering Echo. Queen Farida draws together the desert tribes to conquer the land, even though a prophecy has promised the land to the Gameli tribe. The Gameli journey to the Silver Temple, where the High Priest summons the legendary Maciste from the mountain rock to defeat their enemies and guide them to their promised land.
