The Abominable Dr. Phibes movie poster

 Ten Plagues that befell Egypt in the Old Testament, and wearing a different amulet from a set of ten Hebrew letters that relate to the Ten Plagues, Phibes kills seven doctors and a nurse with the help of his beautiful and silent female assistant Vulnavia (played by actress Virginia North). He has reserved the final punishment for Dr. Vesalius. He kidnaps the doctor's son and places him on a table on which a container full of acid is waiting to destroy the boy's face. A small key implanted near the boy's heart will free him, but Vesalius must perform the surgery within six minutes to get the key before the acid falls. Vesalius succeeds and instead  is sprayed with the acid as the police arrive.
Convinced he has accomplished his vendetta, Phibes retreats to a stone sarcophagus beside the embalmed body of his wife. The Abominable Dr. Phibes movie poster
