The Diabolical Dr. Z

“Nothing ever stripped your nerves screamingly raw like the diabolical Dr. Z”

Irma Zimmer (Mabel Karr), a surgeon, wants the four scientific associates who hounded her father, Professor Zimmer, to his death. She builds a machine that turns people into zombified slaves, then uses it on Miss Muerte (Estella Blain), an erotic dancer whose long fingernails are tipped with poison. Jesús Franco gives the dancer's hands a slow, deliberate menace as she moves toward the first of the four.
