Stars Ramon Gay, Rosita Arenas, Crox Alvarado and Luis Aceves Castaneda. The Angel (a masked superhero) arrives on the scene to try to stop master criminal The Bat (a.k.a. Professor Krupp), who has stumbled onto the cursed relics of the Aztec Mummy. What? Yep. Kinda a Mexican monster movie with a "cliffhanger-action" feel.
