Erika Kohut (Isabelle Huppert) is a piano professor at a Vienna music conservatory. Although already in her forties, she still lives in an apartment with her domineering mother (Annie Girardot); her father is a long-standing resident in a lunatic asylum.

Erika is then wholly sympathetic when the girl's mother (Susanne Lothar) asks for advice on her daughter's recuperation. (The sub-plot of the pupil and her mother, mirroring the main relationship in the film, is absent in Jelinek's novel.) In what clearly qualifies, at that point of the film, as dramatic irony, the girl's mother rhetorically asks Erika who could do something so evil.Walter is increasingly insistent in his desire to start a relationship with her. But when she finally acquiesces, Walter is unwilling to indulge her violent fantasies, which repulse him. The film climaxes, however, when he finally does. He attacks her in her...
