A private nurse comes to work for a retired opera singer, known as The Diva, who is now confined to a wheelchair. The Diva's daughter resents the appearance of the nurse, though she herself is stealing her mother's art collection, replacing the works with prints, and stopping at nothing (not even murder) to hide the evidence of her pilfering. But the tense mother-daughter relations are soon the least of the nurse's concerns, as she comes to believe that the house is haunted.
