September 1977. Maria Callas, a world-famous opera diva in early retirement, lives in a luxurious Parisian apartment with two poodles, a cook and a butler. The job of the first, in addition to cooking, is to give Maria compliments. The second moves a huge grand piano around the house for her from morning to night, counts her pills, picks her up from restaurants and tries to convince her to talk to a specialist instead of hallucinations.
