The plot of this vintage Mexican horror film revolves around a scientist who develops a technique to help people recall their past lives.
Using his daughter as a guinea pig to test his hypothesis, he undertakes the procedure, and she recalls being an Aztec woman who get's sacrificed to the Gods, for having an illicit affair with a warrior.
Not only is she killed- wearing a golden bracelet and breastplate- he is sentenced to be buried alive alongside her, to protect the secrets that surround their ritual deaths.
In order to prove to his theory to his peers, the scientist follows his daughter's directions, to retrieve the golden breastplate, which he plans to use as evidence that his claims are sound.
But, upon doing so, he awakens the mummy sworn to protect it...and initiated it's curse.
A subplot, meanwhile, plays out alongside this, concerning a local villain named the bat, who follows the scientist's every move, with plans to use him to track down a lost Aztec treasure...so he can steal it.
But it plays out rather awkwardly...and seems almost unnecessary...other than to lengthen the runtime a bit.
That aside, it's a pretty decent film, with a message similar to that of The Vampire Bat, which clearly had an influence on this film.
Hence The Bat character as a representation of the Bat God of the Aztecs (itself derived from the Mayan God of the Popul Vuh).
The film conveys a very similar message- as does that film- spun together with the story about Tutankhamun's curse.
The most standout portion of this film, is definitely the great scenery.
Having been shot on location at temples in Mexico City.
And the mummy is pretty cool, as well..with a demeanour similar to that of the monsters from the Blind Dead series.
In the end, it's actually a pretty decent little film, even if it does repackage and repurpose previously established storylines.
And it would go on to spawn it's own trilogy...though...the latter films did not garner the same praise as this one did.
