Erika is a single woman in her thirties, who, despite the best efforts of her mother, did not succeed as a concert musician, but instead works as a teacher at the Vienna Conservatory. I say best efforts, I mean outright pressure. Erika and her mother make for an unusual relationship - the older relying on the glory, company and complete obedience of the younger, the daughter sharing a bed with her mother even at this stage of her life. All this is until a young student at the school decides he will be a younger lover for Erika, and forces his will into the household. But who, should such a relationship actually form, is going to be the power-maker?
