Wrestlers, mad doctors, and human-fish hybrids abound in The Bat Woman (La mujer murciélago), a colourful showcase for the talents of Italian Mexican sex symbol Maura Monti.

When Acapulco’s wrestlers start being murdered and their pineal glands mysteriously extracted, the wealthy luchadora Gloria (Monti) adopts her crime-fighting persona of the Bat Woman. Donning her disguise of shiny blue mask, cape, and micro-bikini, she teams up with agent Mario (Héctor Godoy) to foil the evil Dr Williams (Roberto Cañedo) in his dastardly plan to create an army of amphibious ‘fish-men’.

Produced by Guillermo Calderón (Santo vs. the Riders of Terror) and directed by René Cardona (The Panther Women), The Bat Woman is an eye-popping, high-camp blend of lucha libre and superhero action.
