As they go through their day in their Paris apartment, the long-loving existence of an elderly couple-a film critic (Dario Argento) and a retired psychiatrist (Françoise Lebrun)-is shown via split screen to be bearing the strain of her slow submission to dementia, his struggles with her care as well as his own health issues, and the impact on their already-troubled adult son (Alex Lutz) as he tries to help them cope. Gaspar Noé's remarkable rumination also stars Kylian Dheret. 142 min. Widescreen; Soundtrack: French; Subtitles: English. In French with English subtitles.
