Mesa of Lost Women

“A race of deadly spider-women luring men to their death!”

Spiders the size of people are loose on Zarpa Mesa in Mexico, where Dr. Aranya (Jackie Coogan) works in a hidden lab, injecting them with human pituitary hormones. The women who come into his reach grow strong and unnaturally hard to hurt, the men shrink into twisted dwarves, and Dr. Tucker (Allan Nixon) is left trying to explain it. Herbert Tevos and Ron Ormond shot it in black and white, with Lyle Talbot's narration talking over the desert.
