NARRATOR (Dario Argento): Suzy Bannion decided to perfect her ballet studies in the most famous school of dance in Europe. She chose the celebrated academy of Freiburg. One day, at nine in the morning, she left Kennedy airport, New York, and arrived in Germany at 10:40 p.m. local time.

OLGA (Barbara Magnolfi): Suzy-Sara-I once read that names that begin with the letter S are the names of snakes!

DANIEL (Flavio Bucci): I'm blind, not deaf!

SARA (Stefania Casini): If they don't leave, where do they go?

Dr. FRANK MANDEL (Udo Kier): Bad luck isn't brought by broken mirrors, but by broken minds.

FRANK: She's interested in your favorite subject - witches! Can you tell her something about the mysterious?
DR. MILIUS (Rudolf Schundler): They are malefic, negative and destructive. Their knowledge of the art of the occult gives them tremendous powers. They can change course of events and people's lives, but only to do harm. Their goal is to accumulate great personal wealth but that can only be achieved by injury to others. They can cause suffering, sickness and even the death of those that have for whatever reason offended them.

SARA: Suzy, do you know anything about... witches?

SUZY BANNION (Jessica Harper): Hey, thanks, my room is really pretty.
OLGA: Do you like it? You're sweet, I bet we'll do fine together.
SUZY BANNION: Even if I have the name of a snake?
OLGA: Oh, I was just kidding! Don't tell me you're as touchy as Sara.
SUZY BANNION: No.

MISS TANNER (Alida Valli): I had no idea you were so strong willed. I can see that once you make up your mind about something, nothing will change it for you. My compliments.

HELENA MARKOS: You wanted to kill me! You wanted to kill me! What are you gonna do now, huh? Now death is coming for you! You wanted to kill Helena Markos! Hell is behind that door! You're going to meet death now... the LIVING DEAD!
