Suspiria (1976)

Susie, a young American dance student arrives in Germany (during a rainstorm of biblical proportions) and finds horror at a bizarre ballet school. 

Shortly thereafter a woman is attacked through a window, suffocated, stabbed repeatedly through the heart and dropped through a glass skylight and hanged by a noose.

A second woman is killed by the falling shattered skylight when a broken beam impales her to the floor and a sheet of glass slices her face in half . . . worse still, the Dance School don't have a room ready for the American girl yet.

Luckily, she meets the dentally-challenged handyman and a woman called Olga who is to be her landlady. Susie also has to borrow a pair of dance shoes - Which part of "Dance Student" did she not understand exactly?. She also learns that "names that begin with the letter 's' are the names of snakes" (!?!?!).

The fact that the plot is totally incomprehensible only adds to the hallucinogenic atmosphere. Hypnotic but oh so repetitive and ear-splitting musical track accompanied by a multitude of gratuitous hissings, sighings and groanings which wear thin after the first ten minutes.
