Rahter a stinker of an Australian drama/mystery/horror movie. A young woman is hired to be a night nurse for an elderly former opera star almost always only called "The Diva." The Diva's current nurse and companion, an elderly woman named Clara who is The Diva's sole heir, is unhappy anyone new is being hired.
Clara has taken the job to become independent of her artist boyfriend, who she has left, but remains friendly with him. Initially, it seems The Diva is a decent old lady and Clara an awful person (in fact in an early scene, if not the opening one, we see her kill a man who barges into the house to look at some expensive paintings). Clara does some nasty things evidently meant to encourage the night nurse to leave, if not actually harm or kill her. What she does to a pet goldfish is quite remarkable, if bizarre.
It seems like The Diva has guests (or sounds like it), but Clara denies that there are any. Also suspicious is what happened to The Diva's late sister Bessie.
Everything gets more or less wrapped up in the end. One death is rather silly, as a hatchet that is swung has its head spin 180 degrees mid-swing....
