This is a superb film in which Georges and Anne are octogenarians and both retired classical music teachers. Their daughter Eva (Isabelle Huppert) is also a musician and is very concerned for both her parents: Anne gradually becoming bound to a wheelchair, then bedridden but refusing to go into a home, the situation becomes increasingly worse for the relatively healthy Georges.
This could be a play in that the film is a huis clos involving essentially two people in one flat. As Anne's health becomes increasingly worse and she can't speak, Georges eventually has to resort to euthanasia. Amour? À mort. A wonderful, but so painful, unsentimental love story.
