The Bat Woman
“Noble! Bold! Enchanting! Daring! Invincible! Audacious!”
Wrestlers keep disappearing, and two cops bring in Gloria (Maura Monti), a masked crimefighter known as Batwoman, to find out why. The trail leads to Dr. Eric Williams (Roberto Cañedo), who is draining spinal fluid from his captives to build a race of Gill Men. René Cardona sets the hunt in motion fast, and the scientist's work cuts deep enough that he turns it against the woman sent to stop him.
