The evil Dr. Krupp, once again trying to get possession of the Aztec princess Xochitl’s jewels, builds a robot in order to steal a valuable Aztec treasure from a tomb guarded by a centuries-old living mummy. Starring Ramón Gay, Rosita Arenas, Crox Alvarado. One of those weird, psychotronic Mexican mummy movies where a pile of rags battles a cardboard box robot. One of the great battles of cinematic history.
