La India María must find at all costs in the recesses of a mountain the Magic Black Mirror of Tezcatlipoca, since the spirit of his great-grandfather Moctezuma II ordered her to find it in to prevent the destruction of Mexico. Alonso, a handsome Spanish archaeologist, Bianchi, an antiquities dealer and Brigida Troncoso - an ambitious governor, are aware of the existence of such mirror, of the mysterious treasure of Moctezuma and of María, so all undertake a frantic chase after her to seize the magic glass and the gold.
