With his middle-aged son Jacques (Joël Delsaut, OUR CHILDREN) on the verge of starting over with a new job and fiancee in Chicago, Edmond (Michel Bouquet, COP AU VAIN) finds himself about to lose his independence. Staunchly refusing to visit any of the nursing homes Jacques looks into, Edmond stays in his apartment with his cherished plants and memories of his late wife. He gets on with his visiting caregiver Rose (Florence Loiret Caille, TIME OF THE WOLF) - who has just returned to work after miscarrying a child - about as well as he does with his son, but Rose is persistent and unconventional in getting him to eat and take his medication. When Edmond has a fall, Rose and Jacques argue over his care and Rose's boss puts her back on the sick list rather than firing her for getting personally involved with a patient. Edmond is forced to stay in a nursing home while undergoing physical therapy, so Rose visits and keeps him company (as well as giving him a Discman so that he disconnect from those around him). When Edmond checks himself out of the nursing home, he and Rose discover that Jacques has sold his apartment. When Edmond refuses to return to nursing home, Rose takes him back to her home since she and her husband Marc (Éric Caravaca, SON FRÈRE) have had a fight and he has gone to New York with his partner to get a lucrative contract. As she cares for him physically, he pries into her life and the nursery where belongings and memories of the unborn child are preserved. When Jacques calls Rose in search of his father, she claims not to know of his whereabouts. Edmond's forcible appropriates the titular "little bedroom" as his own room turns out not to be the same kind of violation for Rose as when Marc tried to clean the room out and use it for storage; in fact, they almost fulfill the role of surrogate children for one another (with Rose needing someone to care for while giving Edmond the attention he lacks from his son whose resentment and motives may not be entirely selfish). She finds herself starting to open up and move on just as Marc returns and discovers the truth behind their arrangement.
