French film, with the participation of the incomparable and incombustible Catherine Deneuve and the actor Gustave de Kervern, who plays Antoine, a forty odd year old musician who suddenly decides to put an end to his career. After wandering aimlessly for a few days, he finds a job as a porter. Mathilde lives in the old building, in the Eastern part of Paris where Antoine works. She has taken early retirement, and is generous and involved, splitting her time between social services and the joint owners association.
One afternoon she discovers a worrying crack in the wall of her living room. Bit by bit her concern becomes panic; ¿what if the building comes down? As the days go by, Antoine develops a protective streak, as he worries that Mathilde is slipping into madness. Between blunders and anxieties, the two make a clumsy, funny and caring duo, which may help them through a tough time.
