Solitaire (2020)

Renaud is 85 years old and lives in Paris with his trusty wheelchair/caregiver. He's a loner, stuck in his ways, uncomplainingly trapped for years now on the top floor of a building in Montmartre. He has everything he needs at home anyway; he makes toys and gets his meals and his favorite newspaper, and all's right with the world. But what if a new neighbor appeared on his landing to shake up his routine? A lovely one of the same age, in a wheelchair herself, stuck at home? What if they both felt an irrepressible urge to give up their solitary existences?
