It's the return of G&G Film Club as Em and Lindsay watch the 1968 lucha libre film The Batwoman!

When luchadors begin disappearing en masse, mild-mannered socialite/luchadora/crimefighter Batwoman is on the case.  It's a trail that leads her to Dr. Eric Williams and his nefarious plot to... do something with the pineal gland... that results in him creating a race of gill-men.  Batwoman must battle the gill-men, train the next generation of luchadoras, and outshine her incompetent cop boyfriends all while dressed in nothing more than a Batman mask and a small bikini.
