Also Known As: Dario Argento's Suspiria (1977) (advertising title)

"Bad luck isn't brought by broken mirrors, but by broken minds."
-Franco

A young American woman moves to Europe to study classical dance. She takes her lodging in a school of dance in a kind of college-academy; here the protagonist notices immediately that the inhabitants are very strange characters (beginning from the cold and mysterious manager to her ambiguous "staff"). The girl is direct witness to many odd and inexplicable occurances, but she sees only the beginning of a series of horrors that are to occur. Nightmarish visions (of a monstrous and gigantic man), cryptic "presences", sighs derived from beyond the grave and more gruesome discoveries. Her friend, another student at the academy, that tried with her to clarify the mystery, dies a horrible death. The protagonist is placed under a spell from one of the "staff", so she could not draw nearer to the solution of the enigma that lies nested in the institute. They also attempt to poison her the food, but she recovers, avoids the trap, frees herself, runs away to the outside and returns to look to hopefully understand the mystery. Finally, after being led tthrough a thousand other dangers, the young woman discovers that the academy of dance was founded by the woman Elena Marcos, that was, according to history experts and the studious of the supernatural, a witch. The manager and her assistants are nothing else other than her followers, a sect that continues, through the "presence" of Marcos between those boundaries, to spread the Evil. Returning to the inside of the building, the girl finds a mysterious room, in which the old, horrendous Elena Marcos materializes in front of her.

Almost close to her death, the protagonist has a desperate reaction, and pierces through the witch with a hat pin to the throat. This instantly stops the evil; the diabolic witch melts to nothing, destroyed like dust to the wind, while in the meantime the whole environment is shaken from a kind of infernal demolition. While the young heroin runs away finally out of the academy, the building bursts into flames, as she is finally distant from that dreadful place.
