This entertaining entry in the long-running Mexican fantasy series stars Gina Romand as Frankenstein's daughter, who remains eternally youthful thanks to the blood of young virgins. She's also a mad scientist who mummifies her own aunt (Lucy Gallardo), creates a Frankenstein-like monster called Ursus, and uses a gorilla-like henchman to try draining the superhuman blood of Santo (Rodolfo Guzman Huerta). The heroic, masked wrestler must team up with the hulking, disgruntled Ursus to foil her evil plans. Roberto Canedo co-stars with Carlos Suarez, Carlos Agosti, and Gerardo Zepeda. Director Miguel M. Delgado would contribute several films to the Santo series, including the same year's monster-mash Santo y Blue Demon contra Dracula y el Hombre Lobo.
