Jeanne is a woman who is driven by her very active conscience. She attempts to assuage her idealistic bent by trying out life as a nun, but this doesn't work out. After she leaves the convent, she takes a job at a factory, where the callousness of management spurs her to become a labor activist. Her efforts are marked by great persistence and fervor, but she lacks any kind of diplomacy or persuasiveness, and as the years progress, she manages to alienate everyone in her life. By the end of the film, there is only one way that she can see to resolve the horrible situation she finds herself in.

Her parents and a former lover try to help a woman out of an apparently unjustified catatonic condition.

Three women, three generations, two secrets. In the early 1970s, a bomb exploded on board the Swissair flight 330 to Tel Aviv. Isabelle's husband also died. The young, very pregnant widow feared that her lover, the Palestinian activist Djibril, might be entangled in it ... Now, 47 years later, Isabelle finds out that her granddaughter Anaïs has converted to Islam. But why does the young student keep her new faith secret from the family? Anaïs's mother, Léa, immediately rings the alarm.

Jeannette is a single mother living in a working-class community in Marseilles; she tries to support herself and her two kids on her salary as a check-out girl at a supermarket and lives in an apartment complex where everyone is thrown into close proximity with everyone else. Marius is working as a security guard at a cement factory that has gone out of business; he's also squatting in the building, since the plant is soon to be demolished and he'll be needing his money later on. One day, Jeannette happens by the factory, and spotting several cans of paint, tries to take two of them home with her. Marius spots her and tries to chase her away, while she rails at him with curses against the capitalist system. The next day, an apologetic Marius appears at her doorstep, cans of paint in hand; the two soon become friendly, and a romance begins to bloom, though it quickly becomes obvious that Jeannette's romance novel fantasies are a bit off the mark from what Marius has in mind.
